"Wood-Destroying Organism (WDO) Inspection" course
Welcome to InterNACHI's free, online Wood-Destroying Organism (WDO) Inspection course.
This course teaches the inspector how to inspect for indications of infestation of wood-destroying organisms that may exist in a building using a visual-only examination.
Upon successful completion of this course, the student will be able to:
- describe and sketch the biological aspects of common wood-destroying organisms;
- identify and describe termites, fungi, and common wood-destroying insects;
- communicate treatment and management options for wood-destroying insects;
- methods to prevent termite damage;
- inspect crawlspaces; basements; and foundation structures by following an inspection checklist and WDO form;
- list the critical laws concerning wood-destroying insects; and
- describe the value of the inspection in relation to the real estate transaction.
And, in keeping with InterNACHI's commitment to Continuing Education, this WDO Inspection course is free to all InterNACHI members, and can be taken again and again, without limit.

Credit for sources of information on inspecting and controlling WDOs must go to:
Members of the International Association of Certified Home Inspectors; Land Grant University Extension and research workers; most entomologists who pioneered this work; those who kept training and research alive during the period when the success of synthetic organic pesticides preempted nearly all but control evaluations from the 1940s to the 1960s, and those who persist today; pest control industry workers who held training sessions nationally, regionally and locally where information was disseminated among the experienced and provided to the inexperienced; Environmental Protection Agency personnel who molded modern training and influenced the need for national uniformity in training requirements; state regulatory personnel who cooperated with universities and industry and who strongly emphasized the importance of training; and the few textbook authors in the United States and England who compiled the reference data in the understandable and usable form that allows urban pest management practitioners to be professionals.Information in this course can also be found in various training manuals for commercial WDO applicators developed and publications by the Oklahoma Cooperative Extension Service, Division of Agricultural Sciences and Natural Resources, Oklahoma State University; Texas Agricultural Extension Service, the Texas A&M University System; and University of Nebraska Cooperative Extension; and the University of Nebraska-Lincoln.Also, special thanks go to Dr. Jim T. Criswell, Pesticide Coordinator, Oklahoma State University, Oklahoma Cooperative Extensive Service, Dr. Roger E. Gold, professor and Extension entomologist; Harry Howell, assistant research scientist; Dr. Don L. Renchie, Extension assistant professor; Grady J. Glenn, research assistant; all of the Texas A&M University system; and Murray Walton, staff inspector, Texas Structural Pest Control Board, Dr. Clyde L. Ogg, Extension educator, and Larry C. Schulze, Pesticide Education Specialist, University of Nebraska Cooperative Extension.Specific acknowledgments also go to biological illustrators who graphically render pest and beneficial animals where photos fail: A.D. Cushman, Dean of USDA illustrators; A. B. Wright and Joseph Papp, who have created many illustrations on the topic of WDO; and many anonymous illustrators whose work was stripped of identification through the decades of public use.

InterNACHI... #1 in inspection education.
Some features which make InterNACHI's courses superior to existing continuing education options:
- The course is free for all InterNACHI members.
- The course is written in pure XHTML code for quick loading. The course loads fine on old computers and loads fast, even with dial-up.
- The course is designed using a hierarchal menu coupled with a sequential page navigation. This provides the student with the option to easily repeat areas of weakness.
- The course permits the student to start, stop and restart any part of the course as often as desired.
- There are a variety of images within the course, including diagrams, illustrations and photos.
- The illustrations can be enlarged for clearer viewing by clicking on them.
- The text is integrated into InterNACHI's Inspector Glossary. Rolling over blue-colored terms provides their definition.
- The final exam uses multiple-choice questions that reference the images.
- The course's quizzes and final exam have numerous advantages over traditional exam systems:
- The course, quizzes and final exam incorporate built-in intelligence which identifies and strengthens each student's unique subject weaknesses.
- Not only is each question weighted with regard to score, but each answer is weighted, as well as the correctness of each answer being weighted.
- Answers to easy questions are weighted such that the student is penalized, in terms of score, for answering incorrectly, but rewarded modestly for answering correctly.
- Answers to difficult questions are weighted such that the student is rewarded, in terms of score, for answering correctly, but not penalized for answering incorrectly.
- Answers to questions regarding basic safety, or questions every inspector should know the answer to, are weighted such that the student is severely penalized, in terms of score, for answering incorrectly.
- Upon passing the final exam, the student can print out a Certificate of Completion which is auto-generated in their own name.
The student's (InterNACHI member's) information is recorded on InterNACHI's servers for membership compliance verification, and automatically logs completion into InterNACHI's online Continuing Education log.
