Proficiency Scale
The class of structured profiles describing discrete levels of expertise and performance mastery.
Proficiency scales define levels of performance (what a person does) as distinct from knowledge of specific information (what a person knows) and outline tasks a person can manage and the skills necessary to progressively accomplish explicit competencies at increasing levels of complexity. Proficiency scales: (1) assist in making judgments about the kinds of tasks related to a competency that a person is able to perform; and (2) to compare the abilities of different persons with regard to achievement of those competencies at different levels.
