ExploreAbout this exam
The How to Perform Wind Mitigation Inspections Course is a free, online training and certification course offered by InterNACHI® through its accredited college at internachi.edu. It is written for home inspectors and other individuals who conduct wind mitigation inspections and who need to learn how to complete the Florida Office of Insurance Regulation OIR-B1-1802 form (the 1802 form, or Wind Mitigation inspection form) for homeowners and insurers. It also serves as a reference guide for working inspectors.
The course is approved by the Florida Department of Business & Professional Regulation (DBPR) for twelve (12) hours and by the Florida Construction Industry Licensing Board (CILB) for nine (9) hours, and it carries 16 InterNACHI® CE credit hours. Content runs about 32,000 words with 30 minutes of video, a student book, an inspection and writing assignment, a research and writing assignment, 50 quiz questions spread across 11 quizzes, and a 50-question final exam drawn from a larger pool with instant grading.
The exam covers how wind affects and reacts with buildings, the building envelope, windows, doors and gable end wall construction, roof covering, roof deck attachment, roof-to-wall attachment, roof geometry, secondary water resistance, opening protection, and the photographs, protocols, signatures and documentation an inspector must produce. Preparation means working through the course sequentially, using the quizzes to locate weak areas, and reviewing the images, since final exam questions reference them.
Note: as of April 1st, 2026, Florida has updated wind mitigation and the 1802 form; inspectors who need training on the new form should see the updated course, 2026 Wind Mitigation and the 1802 Wind Mitigation Form.
What you'll study
About InterNACHI Wind Mitigation preparation
Who can take this course, and what does it cost?
The course is free to all InterNACHI members, and the course page describes it as free and online. Non-members are directed to join InterNACHI to access it along with other membership benefits. You will need your username and password to log in and take it.
What is the final exam format?
It is a 50-question final exam drawn from a larger pool. The questions are multiple choice, and the final exam uses multiple-choice questions that reference the images, so expect to interpret diagrams, illustrations and photos rather than only recall text.
How is the exam scored, and is it graded immediately?
Grading is instant. The course, quizzes and final exam use built-in intelligence that identifies and strengthens each student's unique subject weaknesses, and each question, each answer and the correctness of each answer are weighted. Answers to basic safety questions carry severe penalties for incorrect responses.
Can I retake the course or exam if I do not pass?
Yes. The course is free to all InterNACHI members and can be taken again and again, without limit. The course also permits you to start, stop and restart any part of it as often as you want, so you can repeat areas of weakness before trying again.
How long does the course take?
The course page publishes a student work time calculation totaling 36.3 clock hours, rounded to 36.0 clock hours and 36.0 InterNACHI CE hours, or 3.6 CEU. That estimate includes reading, video, quizzes, and both the inspection and research writing assignments.
What is the best order for studying the material?
Follow the course sequence: introduction and how wind interacts with buildings; building envelope influences and damage; windows, doors and gable end walls; getting started and roof covering; roof deck attachment; roof-to-wall attachment; roof geometry; secondary water resistance; opening protection; then photographs required, suggested protocols, and signatures and documentation.
What are common ways candidates lose points?
Skipping the image-based material is a frequent problem, because exam questions reference the images. Another is rushing the quizzes instead of using them to find weak topics. Also, basic safety questions are weighted so that an incorrect answer is heavily penalized, so do not treat them casually.
What do I receive after passing?
Upon completion of the course and passing of the 50-question final exam, you can download and print your own Certificate of Completion, which is auto-generated in your own name. Your information is recorded on InterNACHI's servers and completion is logged into your online Continuing Education log.
Does this course cover the current Florida 1802 form?
The course teaches completing the Florida Office of Insurance Regulation OIR-B1-1802 form. However, as of April 1st, 2026, wind mitigations and the 1802 form have been updated by the state of Florida, and inspectors needing training on the new form should see the updated course, 2026 Wind Mitigation and the 1802 Wind Mitigation Form.
