Generally speaking, a contractor/trade exam requires a score of 70 to pass whereas certification exams require a 75. We strongly recommend you read below for more detailed information on passing scores:
A passing score is the score set by the ICC and/or/with the Exam Development Committee (EDC) as the minimum score needed to pass the exam. This score is technically called a scale score and is set as 75 for the National Certification exams.
Most Contractor/Trades examinations require a candidate to answer at least 70 percent of their questions correctly in order to pass the exam. The Master Electrician examination requires 75 percent of the questions to be answered correctly to pass. It is important that you carefully read the relevant bulletin or contact the licensing agency for information regarding their minimum passing requirement.
For all exams, if you achieve a passing score, you will be notified with the word “PASS.” No numerical score is provided to passing candidates. Your score report will include a Code Council ID number which participating jurisdictions can use to verify your passing status here.
