Smarter Balanced Summative Assessments (SB) is one of the online summative assessments - part of California Assessment of Student Performance and Progress (CAASPP) System.

The summative assessments are comprehensive, end-of-year assessments of grade-level learning that measure progress toward college and career readiness. Each test in English language arts/literacy (ELA) and mathematics is comprised of two parts: (1) a computer-adaptive test and (2) a performance task, administered within a selected testing window available at 66 percent of the instructional year for grades three through eight, and grade eleven.

The summative assessments are aligned with the Common Core State Standards (CCSS) for ELA and mathematics. The tests capitalize on the strengths of computer adaptive testing efficient and precise measurement across the full range of achievement and timely turnaround of results.

California High School Exit Exam:
Show data for

(State average from 2,357 schools)
Beginning with the Class of 2006, students in California public schools were required to pass the California High School Exit Examination (CAHSEE) to demonstrate competency in grade-level skills in reading, writing, and mathematics to earn a high school diploma. The content of the CAHSEE was based on content standards in English-language arts and mathematics that were adopted by the State Board of Education (SBE) in 2003. In 2010, the SBE adopted the Common Core State Standards in English language arts and mathematics. The CAHSEE has been repealed. Assembly Bill 830 was chaptered into law by Governor Brown on October 10, 2017. This law eliminates the CAHSEE and removes it as a condition of receiving a diploma of graduation or a condition of graduation from high school.
