The NEHA REHS/RS examination will report scores using scaled scores that range from 0 to 900 with a passing score of 650. The raw passing score is mathematically transformed so that the passing scaled score equals 650. This process is similar to the way one adjusts Celsius and Fahrenheit temperature scales. While the values may differ the temperatures are the same. For example, water boils at the same temperature regardless of the scale used.
Candidates who pass the examination will earn scaled scores of 650 and above, and those who fail will earn a scaled score between 0 and 649. A scaled score is NOT a percentage score. In summary, a scaled score is merely a transformation of a raw score. Scaling is done to report comparable results when forms and raw passing scores vary over time.
Your score will be based on the number of questions answered correctly. If you are unsure of the answer it is better to guess. You will not be given credit for any question left blank.
Your exam results will be mailed to you from the NEHA office 4-6 weeks after the administration.
If you pass the exam, NEHA will send you a credentialing packet with a score letter, certificate, wallet card and Continuing Education information.
If you fail the exam, NEHA will send you a score letter and a Retake Application. You must wait at least 90 days from your test date before you can retake the exam. To retake the exam, you need to submit the Retake Application and pay the Exam Fee and Computer Test Fee, if you will retake the exam on computer. You do not need to do the whole application again or resubmit transcripts. There is no limit on the number of times you can retake the exam, but you must wait 90 days between each attempt.
