Using CBM To Explore a Consequential Basis for the Validity of a State-Wide Performance Assessment

Abstract

This study examines the consequences of a state-wide performance assessment program using Curriculum-Based Measurement (CBM). CBM reading and writing measures were administered three times during the school year in two fifth-grade classrooms that were participating in a state-wide school accountability program employing an extended performance task. We found significant gains in written expression but no progress in reading. We concluded that this finding probably reflected an increased amount of time spent in classroom writing activities in preparation for the performance assessment. Both CBM and performance assessment are viewed as important tools for building systemically valid classroom assessment programs.
