The Illinois Alternate Assessment (IAA) is the yardstick the state uses to measure the learning of students with the most significant cognitive disabilities. Students take the IAA if participation in the state's regular assessments — the Illinois Standards Achievement Test (ISAT) or the Prairie State Achievement Examination (PSAE) — is not appropriate, even with accommodations.
The IAA is a performance-based assessment that uses on demand tasks.
As of August 16, 2010 the IAA is federally approved.
