When creating tests that define levels of competency as they relate to performance, it’s essential to use a reliable method for establishing defensible pass/fail scores.
One of these is the Angoff Method, which uses a focus-group approach for this process. This method has a strong track record and is widely accepted by testing professionals and courts.
Subject-matter experts (SMEs) review each test question and then predict how many minimally-qualified candidates would answer the item correctly. The average of the judges’ predictions for test questions is used to calculate the passing percentage (cut score) for a test.
Basing cut scores on empirical data instead of choosing arbitrary passing scores helps test developers produce legally defensible tests that meet the Standards for Educational and Psychological Testing. The Angoff Method offers a practical way to achieve this.
