Lazarus, SherylThurlow, MarthaAlbus, Deb2015-08-202015-08-202011-04https://hdl.handle.net/11299/173983A report examining publicly-reported participation and performance data for the alternate assessment based on modified achievement standards (AA-MAS). Analysis included all states publicly reporting AA-MAS data, regardless of whether they had received approval to use the results for Title I accountability calculations. Data were examined for school years 2006-07 through 2009-10. Because most states had not yet reported data for 2009-10, the authors focused most of the analyses on 2006-07 (six states with an AA-MAS), 2007-08 (eight states with an AA-MAS), and 2008-09 (eight states with an AA-MAS).enK-12 educationdisabilityeducational accountabilityeducational assessmenteducational accommodationsReport
