When? April 2nd – May 24th, 2018

Test format? Computer-adaptive (on Google Chromebooks)
Test purpose? From the CAASPP- The California Science Test (CAST) is an online test based on the California Next Generation Science Standards. All local educational agencies (LEAs) with eligible students in grades five and eight will administer a pilot CAST. LEAs with eligible students in high school (i.e., students in grades ten, eleven, or twelve) will be pre-selected and only one grade will participate in the spring 2017 pilot. The CAST pilot uses the current California Assessment of Student Performance and Progress test delivery system and will only be administered online. Students will not receive scores for the pilot test; however, student participation data will be collected and reported for accountability.

Who takes the CAST pilot? Participation in the CAST pilot is required for all students in grades five and eight, and for the pre-selected high school grades with the exception of eligible students who will take the California Alternate Assessment for Science pilot.


From The CSTs for Science are multiple-choice tests. Items on these tests are developed by California educators and test developers and are written specifically to assess students’ achievement of California’s academic content standards in science.
