  • Proper Use of Assessment Results from Common Core State Standards
    Since the Common Core State Standards (CCSS) were released in 2010, nearly every U. S. state has formally adopted these standards in mathematics and English language arts (ELA) and many joined one of two Consortia to develop and implement common tests. Given the high stakes associated with the use of scores from the Common Core Assessment as well as the need for proper diagnosis of student learning, this report focuses on a discussion of three fundamental concerns: (1) score comparability and DIF for multiple groups, (2) the selection of software packages for multiple-group IRT analysis, and (3) CDMs.
