Since 1992, the National Center on Educational Outcomes (NCEO) has analyzed participation and accommodation policies for students with disabilities on state administered assessments. This report focuses on accommodation policies for alternate assessments based on alternate achievement standards (AA-AAS). In addition to presenting a national overview of policies, the authors also address the results of their policy analysis by the four content assessment consortia (PARCC, SBAC, Dynamic Learning Maps, and the National Center and State Collaborative). This summary of the results of their analysis of accommodation policies for AA-AAS is organized under three areas of focus: the terms states used to describe changes in assessment administration, the specific accommodations addressed in policies overall, the accommodations addressed for ELLs and accommodation guidelines provided by states. Detailed information overall and by the four consortia are provided in the report appendices.
