The CAST practice test, released in fall 2018, includes 32 discrete items followed by three performance tasks. There are three performance tasks on the practice test to ensure that a practice performance task is available in all three science domains, although a student may see only two performance tasks during future administrations. All accessibility features except for braille are available. Braille will be made available in January 2019.
More information about the CAST is available on the California Department of Education California Science Test web page at http://www.cde.ca.gov/ta/tg/ca/caasppscience.asp.
