California Alternate Assessments (CAAs)

The summative California Alternate Assessments (CAAs) for English Language Arts/Literacy (ELA), mathematics, and science are administered to eligible students.  The CAAs are for students with the most significant cognitive disabilities and whose individualized education plan (IEP) team has designated the use of an alternate assessment on statewide summative assessments.

Eligible students are those whose disability prevents them from taking the Smarter Balanced Summative Assessments for ELA and mathematics and the California Science Test.

California Science Test (CAST)

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 5 and 8 will administer a pilot CAST.  LEAs with eligible students in high school (i.e. students in grades 10, 11, or 12) 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 5 and 8, and for the pre-selected high school grades with the exception of eligible students who will take the California Alternate Assessment for Science pilot.

State law requires the development of a state test that school districts must give to students whose home language is not English. This test is called the California English Language Development Test (CELDT). The purpose of this test is:
  • to identify new students who are English Learners, in kindergarten through grade 12.
  • to monitor their progress in learning English.
  • to help decide when they are proficient in English.
The new CELDT implementation will be called the ELPAC (English Language Proficiency for California) will take place in Fall of 2018.
