Evaluation of Vertical Scaling for the Alternate English Language Proficiency Assessment

• In Event: Electronic Board Session II

Abstract

Alternate assessments have historically not been developed with the same level of psychometric rigor as the regular assessments developed for general education population. Therefore, schools cannot measure growth across grades or over time. The purpose of this study is to evaluate the new vertical scale by comparing two calibration procedures.
