The California Science Test (CAST) is part of the California Assessment of Student Performance and Progress (CAASPP) system. Click to see more about the MATH and ENGLISH portions of test. 

The CAST assesses student knowledge of three domains: Physical Sciences, Life Sciences, and Earth and Space Sciences. Although the test is untimed (students can take as long as they need) it is expected to take approximately two hours to finish. 

The CAST is taken once in 5th grade, once in 8th grade, and once in High School. In the middle school, students will need to draw on experiences and knowledge gathered throughout grades 6 - 8.
