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 System. The purpose of the CAA for Science is to measure what students know and can do. 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, 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 CAAs are 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).

Scores and Results Reporting

CAA for Science, Year Two Pilot, 2017-18 administration research files contain the aggregated results, which are reported by the state, county, LEA, and school levels as well as by student groups. The data is intended for use by educators or researchers to perform analyses and prepare customized reports. Caution should be used when interpreting the preliminary indicator results, given that these results are from an assessment that was not operational.

Reporting Science Assessments Results—2018–19 Timeline provides LEAs, schools, and other stakeholders with information about releasing the science results to parents/guardians and the public.
