Diagnostic classification models (DCMs) classify examinees based on the skills they have mastered given their test performance. This classification enables targeted feedback that can inform remedial instruction. Unfortunately, applications of DCMs have been criticized (e.g., no validity support). Generally, these evaluations have been brief and…

This review of methods for validating writing assessments was conceptualized within a framework suggested by S. Messick (1989) that included five operational components of construct validation: (1) content representativeness; (2) structural fidelity; (3) nomological validity; (4) criterion-related validity; and (5) nomothetic span.

Reviewed studies focus on philosophical underpinnings and practical guidelines for conducting validity inquiry. Sections describe the emerging consensus on validity inquiry, components of validity…

During a period when the reform-minded are very critical of the degree to which testing is actually related to the conditions for which data are employed, authentic assessment offers the opportunity to evaluate learning in settings closely related to the real world. It also allows the evaluator to tailor assessment conditions for individual…

A concept map is a graph consisting of nodes representing concepts and labeled lines denoting the relation between a pair of nodes (concepts). The external concept map constructed by the student is interpreted as representing…
