California Alternate Assessment for Science

California’s statewide science alternate assessment for students with the most significant cognitive disabilities.

Program Overview

The California Alternate Assessment (CAA) for Science is a part of the California Assessment of Student Performance and Progress (CAASPP) System. The purpose of the CAA for Science is to measure what students know and can do in science. These measures help identify and address gaps in knowledge or skills early so students can receive the support they need.

Only eligible students may participate in the administration of the CAA for Science. Any student identified for alternate testing takes the alternate version of all assessments. The CAA for Science is administered to students in grades five and eight and once in high school (i.e., grade ten, eleven, or twelve). Individualized education program (IEP) teams “shall determine when a child with the most significant cognitive disability shall participate in an alternate assessment aligned with the alternate academic achievement standards.” (Title 1, Part A, Subpart 1, Sec. 1111(b)(2)(D)(ii)(I)—Every Student Succeeds Act, 2015).

The CAA for Science is aligned with alternate achievement standards—called the Science Core Content Connectors—and are linked to the performance expectations from the California Next Generation Science Standards (CA NGSS).

Test Administration

Scores and Results Reporting

CAA for Science, Administration Research Files web page—Due to the coronavirus disease 2019 pandemic, school closures, and the approved federal waiver of testing and reporting requirements from the U.S. Department of Education, many students did not complete testing. As a result, the California Department of Education did not report aggregate or summary results for the 2019–2020 administration.
