        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 pictures of actual roofs.
        • 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:
          1. The course, quizzes and final exam incorporate built-in intelligence which identifies and strengthens each student's unique subject weaknesses.
          2. 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.
            1. 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.
            2. 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.
            3. 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.
