What is the difference between a competency and a proficiency level?

• A. A competency is a measurable behavior or ability
• B. Proficiency level is a static attribute
• C. A competency is a measurable behavior or ability; proficiency level indicates degree of mastery
• D. Proficiency level is unrelated to performance

Answer: (C)

Competency is the defined capability—the observable behavior or ability that someone possesses and can demonstrate. Proficiency level then describes how well that capability is performed, indicating the degree of mastery on a scale (from basic to advanced, for instance). So you assess not just whether someone can do something, but how effectively they can do it. This distinction matters because it links what needs to be demonstrated (the competency) with how well it’s done (the proficiency level), enabling clearer evaluation and targeted development. For example, someone might have the competency to analyze data, but their proficiency level shows whether they perform basic analyses or produce deep, insightful insights. The other statements miss this relationship: one reduces proficiency to a static attribute, which isn’t accurate because proficiency can grow with practice; another claims proficiency is unrelated to performance, which contradicts how performance ratings are built; and while a competency is indeed a measurable behavior, that alone doesn’t explain how proficiency level fits in.
