A Tree-Based Approach to Proficiency Scaling and Diagnostic Assessment.

Sheehan, Kathleen M.

Journal of Educational Measurement, v34 n4 p333-52 Win 1997

A new procedure is proposed for generating instructionally relevant diagnostic feedback. The approach involves constructing a strong model of student proficiency and then testing whether individual students' observed item-response vectors are consistent with that model. The approach is applied to the Scholastic Assessment Test's verbal reasoning test. (SLD)
