This post is really just a link share. I don't know about you, but I often get so wrapped up in teaching physics that I lose track of where the state is in terms of mandated statewide assessments.
Gone is STAR and its CSTs. In development is the California Science Test (CAST), part of the California Assessment of Student Performance and Progress (CAASPP) [No program is legit unless it has a handy acronym or initialism.] So CAST is the product of CAASPP Science.
The skinny: The CAST is for eligible students in grades five, eight, and once in high school. It's currently in development with pilot tests being run. The test will become operational in the 2018-19 academic year.
Here's the California Department of Education's CAST web page.
Here's a link to released practice test items. When I looked, I was disappointed. Perhaps material for a post to follow. Take a look for yourself at Online Practice and Training Tests Portal.
And here's the promotional video offered on that page.
