California Science Test (CAST)

The California Science Test (CAST) is an online assessment based on the California Next Generation Science Standards (NGSS) . All local educational agencies (LEAs) with eligible students in grades five and eight and in high school will administer the CAST operational test. The CAST operational test uses the current California Assessment of Student Performance and Progress (CAASPP) test delivery system and will be administered online only.

Who takes the CAST operational test? The CAST is administered in grades five and eight and once to each student while that student is in high school. All students must take the CAST by the end of grade twelve, but have the option of testing in grade ten or grade eleven. Only eligible students may participate in the administration of the CAST. Students assigned to take an alternate assessment should take the California Alternate Assessment for Science.
