About InterNACHI's Online Inspector Examination

InterNACHI serves governments and regulatory boards by providing an assurance of above minimum standard level of competency of home inspectors, specifically for licensing reciprocity purposes. InterNACHI supports home inspector regulations, intended to protect the public, that require passing of an examination that assesses home inspector competence. InterNACHI's Online Inspector Examination was developed using a blueprint based largely on InterNACHI's Standards of Practice and Code of Ethics, with test methodology based primarily on Standards for Education and Psychological Testing by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education.  InterNACHI's Online Inspector Examination also relies on the Equal Employment Opportunity Commission's Uniform Guidelines for Employee Selection Procedures, the National Commission for Certifying Agencies' Standards for Accreditation, and other applicable standards. 

Note:  InterNACHI has a proctored version used by community colleges and Home Inspection schools.  It is also available for municipalities that require a proctored exam.

 

What is the purpose of InterNACHI's Online Inspector Examination?

InterNACHI's unproctored Online Inspector Examination's main purpose is to serve as InterNACHI's entrance exam. InterNACHI's proctored Online Inspector Examination also has the secondary purpose of serving governments and regulatory boards by providing an assurance of above minimum standard level of competency of home inspectors, specifically for licensing reciprocity purposes.

How many times can I take it?

You can take the free exam as many times as you like, whenever you like, wherever you like. It is different every time. Mathematically there are billions of versions of InterNACHI's Online Inspector Examination.
 
There is no harm in failing our online exam and you can take it as often as you like.  It will reveal where you are weak and what to study.  If you simply can't pass, we recommend ordering the Inspector's Library.  InspectorOutlet also sells all our most popular training books as inexpensive pdf downloads.
 
 

Is the InterNACHI's Online Inspector Examination different every time I take it?

Yes. It is different every time anyone takes it. The 120 questions are generated randomly. The order of the possible answers is random. The 120 questions are drawn randomly from a much larger pool of questions. Some questions are the same, only worded differently. New questions are being periodically added to the pool after psychometrically testing them.
 
 

I heard that InterNACHI's Online Inspector Examination is too difficult. Is this true?

No. The exam is difficult for some and easy for others. A general understanding of residential construction and components is helpful. Some exam takers who have a background in construction are able to pass on the first attempt, even though they have no inspection experience. Remember, if you fail, we can use your exam results to help determine what you need to study. InterNACHI gathers International statistics (link takes a few moments to open) about each question on the exam. These statistics are automatically updated every time someone takes the exam. Statistics concerning level of difficulty are displayed for each question as you take the exam.   Live international statistics (link takes a few moments to open) about the exam, including pass/fail rates, are available on our website.


I heard that InterNACHI's Online Inspector Examination is too easy. Is this true?

No. The exam is difficult for some and easy for others. Only about 30% the people who take the exam for the first time pass. The average grade is failing. You need a score of 80 to pass. InterNACHI gathers International statistics (link takes a few moments to open) about each question on the exam. These statistics are automatically updated every time someone takes the exam. Statistics concerning level of difficulty are displayed for each question as you take the exam. Some of the International statistics about the exam, including pass/fail rates, are available on our website. Critics must recognize that this exam is InterNACHI's entrance exam. Passing the exam is required to join InterNACHI. Other associations have no entrance requirements. Pets and blind men can and have joined other national associations.  Critics should also read http://www.nachi.org/examsthatharm.htm

 

How many questions do I have to answer to pass?

It is not possible to say. The exam uses a weighted scoring system. Each of the 120 questions is weighted based on importance. Questions that have safety implications or cover critical issues count more than questions that have less serious implications or are geographically regional. For example, questions that test to see if you know things every inspector should know are weighted heavily. This weighted system is why your score is a possible 100%, though you will be asked 120 questions.  Frankly, it is one of the main features that make this exam great.

 

Is InterNACHI's Online Inspector Examination a timed test?

Yes. You will be given only 60 minutes to answer 120 questions (30 seconds per question). If you run out of time before you answer all the questions but still answer enough to score 80% or more correctly, you will still pass the exam.

  

Does the exam contain many questions about InterNACHI?

No. It is a well-rounded, general examination to determine the competency of any inspector. The exam is not association-specific. But much more than that, more people have taken InterNACHI's Online Inspector Examination than all other inspection examinations combined. Furthermore, the system has built-in intelligence which constantly calculates and recognizes everything from individual repeat improvement to overall industry knowledge trends. All this combined with constant nationwide expert participation and improvement makes InterNACHI's Online Inspector Examination the industry standard for assessing inspectors.
 
 

I understand that the exam contains many questions about wiring and electricity. Why?

It is true that the exam contains extra questions about wiring and electricity. Although "electrical" is only a small part of a home inspection, it is one of the more important parts. This is because electrical problems, unlike plumbing, for example, can destroy property and kill people.  Safety questions are also weighted heavily.

 
 

I understand that the exam contains some very easy questions and some very difficult questions. Why?

Some questions may appear too easy or too difficult. That is because there are questions on this examination that are not counted toward your score, but are used by InterNACHI to monitor overall knowledge of the industry. Eventually questions that are either too easy or too difficult are removed altogether. 

 

Are the questions true/false or multiple-choice?

Both true/false and multiple-choice questions are used. Each question page has two parts. The first tells you how much time you've spent so far, and how much time you're allowed.  It also tells you how many questions you've answered, and how many there are in total.  A new feature also gives you an idea of how hard the question is by telling you how well other people have done on it. This information is useful, but don't spend too much time on it, as it will slow you down.  The second part is the test question itself. Some questions will be true/false and others will be multiple-choice.

 

Should I skip a question if I don't know the answer?

No. It is statistically better for you to guess than skip, so we have made it impossible to go on to the next question until you pick an answer. Always choose the best answer out of the options given, even if two or more answers seem correct. If you see a question that could be improved or you think is in error, please write it down and contact InterNACHI once you have finished the examination.

 

If I don't run out of time, can I go back and double-check my answers?

Yes. Examinees are given the opportunity to double-check their answers and correct mistakes before they submit them (within the time constraints of the exam).

 

How did InterNACHI determine the passing score of 80%?

InterNACHI used several reasonable methods to come up with this passing score. International pass/fail rates (link takes a few moments to open) are automatically updated every time someone takes the exam, and these statistics are posted (link takes a few moments to open) on our website. It is interesting to note that one of the methods used for setting the passing score, a version of the Modified Angoff Technique, determined the passing rate should be set at 71%.

 

Can't someone just keep taking the exam until they pass?

Our statistics show that immediate-repeat exam takers fare no better over time. InterNACHI has numerous examples of the exam being taken sequentially by the same exam taker without marked improvement. Some exam takers have tried as many as 15 times in the course of one day without establishing a correlation between success and number of attempts. Post-exam interviews show improvement can only come with study between attempts.

 

Can't a computer hacker cheat?

InterNACHI's Online Inspector Examination is very secure. Each exam is dynamically created using advanced randomization techniques. The data is then stored server-side, making it nearly impossible to cheat the system.

 

Is there something I can do to prepare for taking the exam?

Yes. Visit InterNACHI's Online Inspector University. It is free.

 

Is it an open-book examination?

Yes. You may use notes and books.  This statement is included in proctor instructions.  Our exam is difficult to pass, even though it is open book.

 

What will I need to take the exam?

Nothing except a reliable Internet connection. Your time will NOT be extended if your connection fails or if your computer crashes during the test. In the case of a connection failure, you should be able to re-connect and continue from where you stopped. If you cannot, don't worry, because InterNACHI's Online Inspector Examination is completely free, and you can re-take it whenever you wish. If you exceed the test's time limit, the unfinished questions will be counted as incorrect.

 

I only have a dial-up modem and an older browser.  Can I still take InterNACHI's Online Inspector Examination?

The exam is built with the latest server-side technology for increased security, but implements widely compatible client-side technology so that almost anyone with a web browser (new or outdated) can use the system. The system is built with a 56k dial-up modem in mind: If an examinee's connection is lost mid-exam, he/she can simply reconnect and start where they left off. The system also uses optimized, low-resolution graphics for faster page loading.

 
 

Why is InterNACHI's Online Inspector Examination a useful learning tool?

Each question is categorized and cross-categorized. Many questions fall into more than one category. This provides the basis for a narrative and quantitative evaluation post-completion, so that the examinee knows what needs improvement whether they passed the exam or not. The summary even includes a color pie chart.

 

What if I fail InterNACHI's Online Inspector Examination?

Don't worry. Failing the exam will help you learn what you should study to become an inspector.  The exam is free and you can take it as often as you like. You can take the free online exam now, from the comfort of your own home at no charge. It is graded instantly online.  If you simply can't pass, we recommend that you order the Inspector's Library.

 

Is my individual score kept confidential?

Yes. Your privacy and the security of your personal information are very important to us at InterNACHI.  This information is kept confidential, and individual scores are revealed only to the exam taker. Scores do not appear on certificates.  We only use cookies to identify you during the exam.  We do not collect personally identifiable information on our website unless you choose to give it to us. Even if you choose to give us information, we keep it confidential. We do not sell mailing lists or release your information to anyone outside our organization. We only use the information you give us to fill your order, to honor your request, to determine your apparent need, to provide information you desire, or to improve the quality of your experience on our site.  You can be sure that your personal privacy and trust are always safeguarded.

 

What if I pass InterNACHI's Online Inspector Examination?

Great! Passing the exam fulfills one of the requirements needed to join the International Association of Certified Home Inspectors.  Read our Membership requirements.  But feel free to take it just to uncover your weaknesses.
 
 

Why must InterNACHI members pass this exam every year?  Isn't once enough?

No.  Once is not enough.  Our industry changes over time and our exam is a living document that keeps up with changes in the industry.  Associations that permit members to maintain their membership without passing an exam every year or so are... suspect.  Read our Membership requirements.

 

What if I barely pass InterNACHI's Online Inspector Examination?

Don't worry. Passing is passing. Your score is computed and revealed to you at the end of the exam.  However, your score is not reflected on your certificate. There is no reason to keep taking the exam in order to try to achieve a higher score, unless, of course, you find it fun!

 

I have taken several different home inspection exams. Why does InterNACHI's Online Inspector Examination feel easier than other exams?

InterNACHI's Online Inspector Examination feels easier for several reasons:

  • It is free, so there is no financial pressure to pass.
  • You can take it from the comfort of your own home.
  • You can take it again and again (it is different every time).
  • There are no irrelevant questions (found in other similar exams).
  • It is not association-specific.
  • It intentionally includes easy-to-answer questions (exam takers are penalized severely in terms of score for answering these questions incorrectly, but not rewarded for answering these questions correctly). 

International statistics about InterNACHI's Online Inspector Examination are available online and automatically updated every time someone takes the exam.

 

Does InterNACHI accept any other exams as alternatives to InterNACHI's Online Inspector Examination?

No.

 

I need to pass an additional state exam. Can InterNACHI help me pass?

A few states require the passing of an additional state exam. InterNACHI will help you pass your exam.

 

I need to have InterNACHI's Online Inspection Examination proctored. Do you offer a proctored version?

Yes. InterNACHI's Online Inspector Examination has been proctored for many years by InterNACHI, home inspection schools, as well as community colleges. You can also use a proctor of your choosing, provided he/she is a licensed, practicing teacher or professor and is not your spouse, parent or relative.  Email Nick for details and the correct form. 
  
 

Was InterNACHI's Online Inspector Examination developed in accordance with accepted psychometric standards?

Yes, but much, much more than merely being developed in accordance with accepted psychometric standards (which was simple), InterNACHI's Online Inspector Examination has numerous built-in technologies developed by InterNACHI that makes it the industry's best determinator of inspector competence, by far.
 
InterNACHI's Online Inspector Examination was developed by InterNACHI over many years, measures competence in home inspectors based on the critical job components and delineated skill sets from Standards of Practice, Code of Ethics, interviews, mock inspections, surveys, observations, group discussions, and data collected from some 430,000+ exams already taken.  With the industry's most popular exams, quizzes and online education, combined with its 255,000-page website and 500,000-post message board (both the largest in the industry), InterNACHI, the largest home inspection association in the world, collects and possesses more home inspection exam question/answer data and industry information than all other private and government entities combined. 
 
Unlike other home inspection examinations that may use a panel of experts (if at all) to review and validate each question once, InterNACHI's Online Inspector Examination exploits its ongoing access to almost every expert in the field.  The questions/answers and any related performance issues stand the test of time under the industry scrutiny demonstrated in InterNACHI's message board, InterNACHI's open-to-all existing exams and quizzes, InterNACHI's online education, InterNACHI's exam prep tools, InterNACHI's expert trainers/educators, and InterNACHI's various professional committees. 
 
In essence, everything the industry knows, every question ever asked to test that knowledge, and every right and wrong answer ever given to those questions are forever examined to verify technical accuracy and content validity.  Other existing home inspector examinations admit that their content is based solely on one old role delineation study.  Exploitation of InterNACHI's massive data collection abilities has permitted the build-up of a supplemental bank of psychometrically sound items (questions) that are rotated into the InterNACHI's Online Inspector Examination pool, replacing obsolete items with items of similar content and difficulty.  This is especially important in the inspection industry where the pool of items used in licensing exams is widely known and circulated.  The massive culling of this industry-wide data also provides a vast, published item reference in support of legal defensibility.  InterNACHI's exam system's built-in intelligence constantly and automatically calculates and recognizes absolutely everything from individual repeat improvement to overall industry knowledge trends.
 
InterNACHI's Online Inspector Examination was developed using a blueprint based largely on InterNACHI's Standards of Practice and Code of Ethics, with test methodology based primarily on Standards for Education and Psychological Testing by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education.  InterNACHI's Online Inspector Examination also relies on the Equal Employment Opportunity Commission's Uniform Guidelines for Employee Selection Procedures, the National Commission for Certifying Agencies' Standards for Accreditation, and other applicable standards. 
 
InterNACHI's Online Inspector Examination is an open-book exam.  Exam takers are free to bring and use any written notes or printed (non-digital) reference material during the exam; however, use of Palm Pilots or laptops is prohibited.  Calculators are also prohibited and unnecessary.  The items in InterNACHI's Online Inspector Examination are biased toward application, analysis, dynamic problem- solving, and defect-recognition where the exam taker demonstrates learning at a higher cognitive level by applying his/her knowledge on new material.  New material includes a referenced photo or diagram or a situational/hypothetical stem question.  InterNACHI's Online Inspector Examination can be administered open-book, as it simulates the situations home inspectors face every day.  Biasing InterNACHI's Online Inspector Examination toward application, analysis dynamic problem-solving and defect-recognition gives the exam a high degree of validity for predicting inspector success in the field.  Other existing home inspection licensing exams are based on recall.  Such minimum standard exams do nothing more than test the exam taker's ability to remember the correct answers and re-state facts.
 
Because InterNACHI is already the largest provider and administrator of home inspection exams and quizzes, inappropriate, poorly worded, ambiguous or questionable questions and/or answers are quickly recognized and revised or removed from future versions.  In addition, new items are developed as the industry evolves.  With the exception of the lightly weighted content domain industry terms, InterNACHI's Online Inspector Examination minimizes the effects of ancillary skills (such as terminology familiarity) by using commonly used phrases, including synonyms, where available.  This also minimizes the effect of geographic bias so prominent in the inspection industry.
 
Each stem question in InterNACHI's Online Inspector Examination is meaningful in and of itself.  In other words, the questions are worded so that the exam taker could predict the correct answer after merely reading the question.  For instance:
Q. Radon... 
A. exposure increases one's chance of contracting lung cancer. 
 
would be worded as follows: 
Q. Radon exposure increases one's chance of... 
A. contracting lung cancer. 
(Note that this is not an actual item found on InterNACHI's Online Inspector Examination.)
 
Negatively stated questions appear on InterNACHI's Online Inspector Examination only when necessary.  For instance, while technically correct, "should not slope downward" would be worded "should slope upward" on InterNACHI's Online Inspector Examination.  Negative stems that include terms such as "except for" or "does not include" are avoided in InterNACHI's Online Inspector Examination.
 
Because use of "all of the above" and "none of the above" should not be used as distracters (incorrect answer options), InterNACHI's Online Inspector Examination does not incorporate such answer options at all. 
 
Because very few things in professional settings are "always" or "never" true, InterNACHI's Online Inspector Examination uses such terms judiciously.
 
InterNACHI formally and informally validates every question and every answer choice (correct and incorrect).  Each item is validated to ensure that the knowledge and/or skill tested by the item is essential for one to pass, validated to assure that the keyed correct answer is, in fact, correct without ambiguity, and validated to ensure that the incorrect answer options are, in fact, incorrect, but still plausible enough to provide distraction.  Distracters (incorrect answer choices) found within InterNACHI's Online Inspector Examination are not tricky or deceptive, but instead employ common errors.
 
As part of the psychometric analysis performed on the InterNACHI's Online Inspector Examination, each question's pass/fail rate is calculated and recorded each time the question is answered so that the question difficulty is quantified over time.  Regular checks comparing the answers given by experienced, skilled inspectors with those offered by inexperienced, unskilled inspectors verify that each question contributes to testing the exam taker's competency.  Also, at the end of every exam session, descriptive statistics customized to each exam taker are displayed, along with a color pie chart depicting that particular exam taker's weaknesses.
 
InterNACHI's proctored Online Inspector Examination is proctored by the International Association of Certified Home Inspectors (InterNACHI), home inspector schools, and community colleges in various locations throughout North America.  One may take InterNACHI's Online Inspector Examination as often as one wishes, with no wait period between attempts.  Proctored exam takers must bring and present photo identification.  Acceptable forms of photo identification include a driver's license, state identification card, passport, or military ID. 
 
Exam takers are free to drink beverages during the exam.  Exam takers are free to take a break during the exam, but the time clock does not stop.  It is unlikely any exam taker will need more than the time limit given, even with breaks.  Obviously, exam proctors and administrators are unable to help with answering questions found on the exam, and exam takers may not talk with each other during the exam.
 
All of InterNACHI's Online Inspector Examination testing facilities meet guidelines that ensure handicap accessibility, quiet and security, and comply with the provisions of the Americans with Disabilities Act by accommodating exam takers who, because of a disability, need special arrangements. 
 
Even though each item on InterNACHI's Online Inspector Examination has only one correct or clearly best answer, InterNACHI's Online Inspector Examination scoring system permits modest reward for the next-best answer choice, and severe penalty for the very wrong answer choice.
 
InterNACHI's Online Inspector Examination scoring system is much more advanced than existing home inspector exams to the benefit of public safety.  Each item is validated to determine the relative importance on assessing the exam taker's knowledge and skill, as is each answer to each question.  Then each is weighted accordingly.  Not only are the questions in InterNACHI's Online Inspector Examination weighted, the answers are as well, in the sense that an exam taker is penalized severely (in terms of score) for incorrectly answering questions that indicate that he/she could cause physical harm to the public, but not greatly rewarded (in terms of score) for correctly answering such questions.  This same scoring is used for questions that test minimum competency.  Likewise, difficult questions (questions that lie outside or nearly outside the scope of a home inspection) are weighted such that the exam taker is not severely penalized for answering incorrectly.  Other existing home inspector exams' questions and answers are all weighted the same in terms of scoring. 
 
InterNACHI's Online Inspector Examination was developed based on the American Educational Research Association, American Psychological Association, and the National Council on Measurement in Education's Standards for Educational and Psychological Testing, the Equal Employment Opportunity Commission's Uniform Guidelines for Employee Selection Procedures, the Civil Rights Act of 1991, and the Americans with Disabilities Act of 1990.
 
InterNACHI's Online Inspector Examination is the industry standard for assessing inspectors.
 
 

How many exam takers pass? How many fail? What is the average grade? What is the average passing grade?

These International statistics are on our website and are automatically updated every time someone takes InterNACHI's Online Inspector Examination.

 

Has InterNACHI formed a partnership with home inspection schools and community colleges to administer the exam?

Yes. InterNACHI has formed partnerships with many community colleges that offer inspection courses across the North America. The purpose of these partnerships is to create and offer quality home inspection courses and Continuing Education credits at the college level.

 

How does InterNACHI's Online Inspector Examination differ from other national inspection exams?

  • InterNACHI's Online Inspector Examination is free to all.  Other national examinations charge a fee each time you take them.
  • InterNACHI's Online Inspector Examination is built with the latest server-side technology for increased security, but implements widely compatible client-side technology so that almost anyone with a web browser (new or outdated) can use the system from anywhere.  Proctoring is available everywhere, too.  Other examinations require you to travel.
  • InterNACHI's Online Inspector Examination is different every time you take it. Mathematically speaking, there are billions of versions of InterNACHI's Online Inspector Examination. Other exams only have only one or two versions.
  • International statistics about InterNACHI's Online Inspector Examination are automatically updated every time someone takes the exam, and these statistics are publicly posted instantly for all to see. Other national examinations refuse to release even their pass/fail rates.
  • InterNACHI's Online Inspector Examination's pool of questions is compiled from submissions by experts and actual inspectors from all associations. Other exams have used only members of one association to produce their pool of questions.  InterNACHI's Online Inspector Examination is a living document that constantly evolves.
  • InterNACHI's Online Inspector Examination is the official InterNACHI entrance exam. Other associations allow anyone to join without taking any exams.
  • You can take InterNACHI's Online Inspector Examination from the comfort of your own home with a dial-up modem. If an examinee's connection is lost mid-exam, he or she can simply reconnect and start where they left off.
  • InterNACHI's Online Inspector Examination uses optimized, low-resolution graphics for fast page loading.
  • InterNACHI's Online Inspector Examination is not about InterNACHI. It is not association-specific like other exams.
  • InterNACHI's Online Inspector Examination was built with scalability in mind. Each question (and its answer) includes image support so that images can be added for further illustration. Each question can also support an unlimited number of answers for further scalability.
  • InterNACHI's Online Inspector Examination permits examinees the opportunity to double-check their answers and correct mistakes before they submit them (within the time constraints of the exam).
  • InterNACHI's Online Inspector Examination uses a weighted scoring system. Questions that have safety implications or cover larger issues count more than questions that have less serious implications or are geographically regional. In other words, questions that test to see if you know things every inspector should know are weighted heavily. Questions that test to see if you know things that are near the outside of the scope of a home inspection, or newly introduced, untested questions are weighted lightly. Other exams count each question equally.
  • InterNACHI's Online Inspector Examination is very secure. Each exam is dynamically created using advanced randomization techniques. The data is then stored server-side, making it nearly impossible to cheat the system.
  • InterNACHI's Online Inspector Examination produces a custom evaluation screen which summarizes your areas of strength and weakness. The summary even includes a color pie chart. Other exams offer little or no summary.
  • InterNACHI's Online Inspector Examination (a living document) is developed in accordance with accepted psychometric standards, ensuring an unbiased, valid and reliable assessment of inspector skill, knowledge and experience. InterNACHI uses a full-time former university research analyst to monitor the exam.  Other examinations are very association-specific and never evolve.
  • InterNACHI used several reasonable methods to come up with our passing score of 80, including a version of the Modified Angoff Technique.  It is interesting to note that this method determined our passing score should be set at 71.  It is also interesting to note that the average score is failing.
  • InterNACHI's Online Inspector Examination's pool of questions and answers were not each drawn subjectively from a single reference, but are generated using input from inspectors and experts from all over the country.  Possible answers and the actual wording of the questions are also subjected to this industry-wide scrutiny.  InterNACHI's Online Inspector Examination is a living document that keeps up with the times.
  • More people have taken InterNACHI's Online Inspector Examination than all other inspection examinations combined. Furthermore, our system has built-in intelligence which constantly calculates and recognizes everything from individual repeat improvement to overall industry knowledge trends. All this combined with constant nationwide expert participation and improvement makes InterNACHI's Online Inspector Examination the industry standard for assessing inspectors.
