CAASPP - California Assessment of Performance and Progress
California's Science Assessments
The new science assessment is known the California Science Test or CAST. The alternate science assessment is known as California Alternate Assessment for Science or CAA-Science. Both CAST and CAA-Science are part of the larger statewide system of assessments know as CAASPP - the California Assessment of Performance and Progress.
2018 CAST and CAA Science Test Results
On December 10, 2018, CDE released the results from the 2018 administration of the CAST field test and CAA-Science Year 2 Pilot. The aggregate results are available on the CAASPP Results Web site at the state, county, LEA, and school levels for all students and by student groups. The results include a "preliminary indicator." Preliminary indicators offer a general indication of student content knowledge. The results include a percent of items answered correctly on machine-score items and an indicator category. They are not scale scores and are not achievement levels. The scores are also not comparable between students, schools, or LEAs, as not all students took the same test.
It is important to remember that 2017/18 was a field test year. This means that the test was still in development when it was administered it to your students. This is normal. What is not normal is reporting these results to families because they are not precise enough to gauge performance at the student level. CDE is fulfilling a requirement by the federal government to provide results to families. The preliminary indicators may be used to inform LEAs about the progress of local implementation of CA NGSS. Results should be leveraged where possible to advocate for additional investment in the implementation of the standards, including professional development.
Preliminary Indicator Levels
- 3: Student performance suggests a considerable understanding of the California NGSS
- 2: Student performance suggests a moderate understanding of the California NGSS
- 1: Student performance suggests a limited understanding of the California NGSS
A complete timeline of the release of the preliminary indicators, including the audience and agency responsible for distributing the information is available from CDE. LEAs are responsible for providing assessment preliminary indicators to parents/guardians. Access the Toolkit A timeline for the release of the test results is also available.

You Can Be Involved!
CDE is recruiting classroom science teachers to participate in item writing, item review, and other science assessment development activities. If you would like to be involved in developing California's new science assessment, register yourself today:
Since their initial release in 2013, there has been a great deal of effort put forward to develop assessments of all types aligned to the Next Generation Science Standards (NGSS). Here are a few resources relating to assessing NGSS that may prove useful. Their inclusion in this list is does not constitute an endorsement or a recommendation from CSTA.

Updates from CDE
On September 28, 2017, the California Department of Education hosted its annual "North/South" Assessment Meeting in Sacramento. Videos from that meeting are available on CDE's website. Two presentations relating specifically to science assessment were presented and the Power Point presentations from that meeting are linked below.
