ICC M1

It is a multiple-choice examination administered through ICC's credentialing program. ICC schedules and delivers exams through its PRONTO system and publishes the authoritative exam listing in the Exam Catalog, so confirm the current delivery method there before you schedule rather than relying on secondhand descriptions.

ICC does not state those figures in the certification pages summarized here, and item counts and time limits are revised periodically. Treat any number you hear from a colleague as unverified and check the Exam Catalog and your PRONTO appointment details for the figures that apply to your exam date.

The passing score is not published in the source material for this page, and ICC can change scoring methodology. Do not build a study plan around a rumored percentage. Your appointment confirmation and the exam administration materials in ICC's Exam Resources section are the reliable sources.

Four roughly equal areas: general administration, definitions and referenced standards; heating and ventilation equipment and appliances; air conditioning, refrigeration and cooling systems; and duct systems, chimneys, vents and combustion air. Expect questions that apply definitions and exceptions rather than ask you to recite section numbers.

ICC maintains published rules and policies covering exam administration, including retake and waiting-period provisions. Review ICC's Admin Rules and Policies and the Candidate Requests/Forms page before your first attempt, so you know the retake process and any waiting period in advance instead of after a disappointing result.

ICC offers reciprocity for various certifications from the NCPCCI and ProBoard Accredited Fire Inspector I and II certifications, and provides transitions for California-related certifications and the 85-Structural Steel and Welding Special Inspector certification. Check the Reciprocity/Transitions page to see whether anything you hold applies to the M1 path.

The certification pages summarized here do not state a validity period, so do not assume a specific number of years. ICC maintains a Maintain/Renew Certification page that lists current renewal requirements, and you can verify your status using the Search for Certified Professionals tool.

Start with administration, definitions and referenced standards, because those provisions set the scope, the terms used in every later question, and which standards are incorporated. Then work through heating and ventilation equipment, cooling and refrigeration systems, and finally duct, chimney, vent and combustion air provisions, which depend on the earlier chapters.

Rushing questions that hinge on an exception, a definition, or an incorporated referenced standard; studying only equipment chapters and skipping administration; and never practicing how to locate a provision quickly in the code book. Practicing with the index, tables and cross-references under timed conditions fixes most of these errors.
