The RESNET National Rater Test is an on-line 55 question multiple-choice test. The test is open book and raters have two hours to complete the test. The test is based on building science concepts and rating procedures. Raters receive the results from the test immediately after completing the test. The passing threshold is 40 out of 55 questions. The test must be administered by a RESNET accredited Rater Training Provider. The testing fee is $125.00.

How the RESNET Rater Test Was Developed
Early in the process, every item in RESNET’s question bank was edited and reviewed by volunteer Subject Matter Experts (SME) with the guidance of a psychometric consultant. This step alone Improved the test by simply eliminating poorly worded question stems and using plausible-but-definitely-not-correct distractors.
Once the item bank was updated with new and improved questions, RESNET’s psychometric consultant created three new fixed-form exams. This is a change from the previous test methodology, in which question items were randomly assigned (weighted by category) from a database. The primary reason for moving away from this method is that with a random collection of questions, one Candidate may draw a more difficult set of questions than another. For the new test, passing scores were determined through a Pass Point Study consistent with procedures adopted in the Standards for Educational and Psychological Testing (AERA, APA, NCME, 1999) and with standards published by the National Organization for Competency Assurance (NOCA). With training and guidance from the psychometric consultant, volunteer SMEs applied the Modified-Angoff procedure to rate the difficulty of every item in the bank by responding to the following question: “What percentage of candidates who are just barely qualified for certification will answer this item correctly?” After statistical analysis of the SME responses, the passing score of 40 was recommended by the psychometric consultant for all three test forms.
