California science test (cast)

Each year, students in grades three through eight and high school participate in the California Assessment of Student Performance and Progress (CAASPP). Every student must take the California Science Test (CAST) once in high school. 

The following student groups will take the California Science Test (CAST) this year:

  • Juniors enrolled in a DVHS science course

  • ALL seniors (whether enrolled in a science course or not) 

  • Testing will be in April, see schedule to the right

This assessment is an online test that measures what your student knows and is able to do. The test includes many different types of questions that allow students to interact with the test questions. Results are published on a student’s academic transcript. 

You are an important part of your child’s education. To help your child get ready for the test you can:

  • Talk about the test with your child. Make sure they are not scared or anxious.

  • Tell your child that you and their teacher have high expectations and are both there to help, every step of the way.

  • Make sure your child gets a good night’s sleep and a nutritious breakfast before testing on these days: seniors NOT enrolled in a DVHS science course - April 1 or 2*; juniors and seniors enrolled in a DVHS science course  - April 15 & 16. 

  • Students will take the test in their regularly scheduled Science class. 

To learn more about the assessment, go to the California Department of Education Parent Guides to Understanding web page.

You also can look at sample test questions on the practice tests on the CAASPP Web Portal

If you have questions, please contact Sarah Landry at 


The CCCs identify priorities in each content area to guide the instruction for students in this population and for the alternate assessment.


*Seniors not enrolled in a DVHS science course will be notified via Loopmail 1 week prior to test when & where to report for CAST testing.
