States with an alternate assessment based on modified achievement standards (AA-MAS) that received a flexibility waiver from some of the requirements of No Child Left Behind are required to phase out their use of this assessment. And, on August 23, 2013, the U.S. Department of Education published a proposed rollback of regulation that allowed the AA-MAS. Not all states developed an AA-MAS. Sixteen states offered this optional assessment between 2011 and 2013. Many, but not all of these states, also belonged to one of the two Race to the Top Assessment (RTTA) consortia that are developing new general assessments--the Partnership for Assessment of Readiness for College and Careers (PARCC) and the Smarter Balanced Assessment Consortium (Smarter Balanced). This Brief addresses the need for consortia to assist their member states in moving away from the AA-MAS. It focuses on key considerations for consortia as they address the inclusion of low-performing students in all member states, informed by the lessons learned from the AA-MAS. Topics highlighted in this brief are: including low-performing students in field test designs, customizing non-summative assessments to include low-performing students, and collecting and examining data on this group of students.
