This assessment option is for a small group of students with disabilities who can make significant progress but may not reach grade-level proficiency within the time period covered by their Individualized Education Program. Students who participate in an AA-MAS must have access to grade-level content. States are not required to offer this option. This report compiles, analyzes, and summarizes states' participation guidelines for the AA-MAS.enK-12 educationdisabilityeducational accountabilityeducational assessmenteducational accommodationsReport
