Registry exams include non-scored questions; approximately what percentage are non-scored?

• A. 20% or more
• B. 5%
• C. 0%
• D. 50%

Answer: (A)

Non-scored questions are included on registry exams as pilot items to evaluate how new questions perform before they’re used for scoring. The goal is to gather enough data on these questions without affecting a candidate’s result, so they’re mixed with scored items and often indistinguishable. The typical proportion is about twenty percent or more, which provides a solid sample to analyze reliability and validity while keeping the test length and scoring intact. This balance helps ensure future exams are fair and accurate.
