California Science Test

California's statewide science assessment for students in grades five and eight and once in high school.

Program Overview

The statewide California Assessment of Student Performance and Progress (CAASPP) System includes federally required science assessments in grades five and eight and once in high school (i.e., grade ten, eleven, or twelve).Since the adoption of the Next Generation Science Standards for California Public Schools, Kindergarten Through Grade Twelve (CA NGSS) in 2013, the California Department of Education has been developing a new science assessment—the California Science Test (CAST)—aligned with these standards.

All eligible grade twelve students must take the CAST if they did not participate in the 2017–18 CAST field test. In addition, local educational agencies (LEAs) have the option to test any or all students in grades ten or eleven; however, it is recommended that LEAs select grade ten or eleven students who are enrolled in their last high school science course. Note that once a high school student takes the CAST, that student is ineligible to take the test again.

The following links provide additional information about the program:

Scores and Results Reporting

The CAASPP website will contain the preliminary indicator summary results for the 2017–18 administration of the CAA for Science, year 2 pilot in fall 2018. Those aggregated results will be reported by the state, county, LEA, and school levels as well as by student groups. Caution should be used when interpreting the preliminary indicator results, given that the assessments are not yet operational.

Reporting Science Assessments Results—2017–18 Timeline provides LEAs, schools, and other stakeholders with information about releasing the science results to parents/guardians and the public.
