Connecticut's Alternate Assessment System is composed of the following assessments for eligible students with significant cognitive disabilities:
- Connecticut Alternate Assessment (CTAA) for English language arts and Mathematics for eligible students in Grades 3-8 and 11
- Connecticut Alternate Science (CTAS) Assessments for students in Grades 5, 8 and 11
Students with significant cognitive disabilities are identified for participation in the Alternate Assessment System when the Planning and Placement Team (PPT) determines the student meets eligibility criteria. Trained teachers administer the Alternate Assessments individually to eligible students.
