California Science TestCalifornia's statewide science assessment for students in grades five and eight and once in high school.
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 developed the California Science Test (CAST), which is aligned with these standards.
High school students will have only one opportunity to take a science test (i.e., in grade ten, eleven, or twelve). Local educational agencies (LEAs) can elect to administer a science test to students in grade ten or eleven. Students in grade twelve, who have not yet taken a science test, will automatically be registered to test. Students repeating grade twelve are not eligible to test.

Scores and Results Reporting
The CAST Reporting Achievement Level Descriptors (ALDs) (PDF) document provides descriptions of the four levels possible for a student’s overall performance on the CAST and the three levels possible for a student’s performance by science domain.
CAST Scale Score Ranges provides the scale score ranges by grade and achievement level.
CAST 2017–18 administration research files contain the results from the 2017–18 field test. CAST aggregated results are reported by the state, county, LEA, and school levels as well as by student groups. These research files are 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 Timeline provides LEAs, schools, and other stakeholders with a timeline for reporting the science results to parents/guardians and the public.
Laws, Regulations, and Requirements
CAST Blueprint (PDF) was used to build the 2018–2019 and 2019–2020 assessments.
Revised CAST Blueprint (PDF; 2MB) will be implemented with the 2020–21 administration of the CAST.
