States must also develop an Alternate Assessment on Alternate Academic Achievement Standards (AA-AAAS) for students with significant cognitive disabilities who are unable to take the regular test (Lashley, 2002; Roeber, 2002; Forte et al. 2016). The mandate is designed to ensure only students with the most significant cognitive disabilities are assigned to take AA-AAAS (Thurlow, Lazarus, & Christensen, 2008).
