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 field test. (Additional information about high school grade assignments is forthcoming.) The CAST field test uses the current California Assessment of Student Performance and Progress (CAASPP) test delivery system and will be only administered online. Students will not receive scores for the field test; however, student participation data will be collected and reported for accountability.
