Illinois Alternate Assessment (IAA)
The Illinois Alternate Assessment (IAA) is the yardstick the state uses to measure the learning of students with significant cognitive disabilities. Students with severe disabilities take the IAA if participation in the states regular assessments - the Illinois Standards Achievement Test or the Prairie State Achievement Examination - is not appropriate, even with accommodations. The IAA test is a performance-based assessment that uses appropriate tasks which are aligned to the Learning Standards. Students are tested in reading, mathematics, science and writing at the appropriate grades.
