Aggregating Interim Assessment Scores for Summative Decisions: Exploring Longitudinally-Weighted Proficiency Estimators

• In Event: Student Growth

Abstract

Competency-based assessment programs consisting of multiple, shorter, interim assessments rather than a longer summative assessment have garnered recent attention. Little consideration has been given to how interim scores are aggregated to produce summative scores. We propose and evaluate four IRT-based longitudinally-weighted proficiency estimators. Implications of weighted scoring are discussed.
