Understanding California School Testing Requirements

California's school testing system is designed to measure student progress, support instruction, and help schools meet state and federal accountability rules. As of today, the main statewide testing programs in California include the California Assessment of Student Performance and Progress (CAASPP) and the English Language Proficiency Assessments for California (ELPAC). These assessments are used differently depending on a student's grade level, language status, and educational program. The California Department of Education (CDE) continues to publish current guidance and testing updates for the 2025-26 and 2026-27 school years. ([cde.ca.gov](https://www.cde.ca.gov/TA/tg/ca/))

For families, the most important point is that California testing is not one single exam. Instead, it is a system of required assessments that may include English language arts, mathematics, science, English language proficiency, and other specialized tests. The exact requirement depends on the student's grade and whether the student is identified as an English learner or qualifies for alternate assessments.

What Students Are Tested in California?

Most students in grades 3 through 8 and grade 11 take the Smarter Balanced Summative Assessments in English language arts and mathematics. California also uses the California Science Test for certain grades, and students with significant cognitive disabilities may take the California Alternate Assessments instead of the general assessments. The CDE's academic indicators page confirms that these assessments are part of the state's accountability system for grades 3-8 and 11. ([cde.ca.gov](https://www.cde.ca.gov/Ta/ac/cm/dashboardacad.asp))

In practical terms, this means California schools are expected to test students in the grades required by the state, and schools are also measured on participation rates. The CDE notes that participation matters for the California School Dashboard, which is one reason districts work hard to make sure eligible students complete the required tests.

English Learner Testing: ELPAC Requirements

One of the most important California testing requirements involves English learners. Students whose primary language is not English are given the Initial ELPAC to determine whether they are English learners. After that, enrolled English learners must be assessed annually with the Summative ELPAC or Summative Alternate ELPAC until they reclassify. The CDE's 2026 requirement letter states that the annual summative testing window runs from February 1 to May 31. ([cde.ca.gov](https://www.cde.ca.gov/ta/tg/ep/initialelpac.asp))

This annual English language proficiency testing is not optional for schools. The CDE says local educational agencies are required to assess each enrolled English learner every year, and participation below 95 percent can affect accountability results on the California School Dashboard. That makes ELPAC one of the most closely monitored testing requirements in the state. ([cde.ca.gov](https://www.cde.ca.gov/sp/ml/elpacrequirmnts26.asp))

How California Handles Alternate Assessments

California provides alternate assessments for students with the most significant cognitive disabilities. These students may take the California Alternate Assessments in place of the general CAASPP tests when they meet the state's eligibility criteria. The CDE's CAASPP materials describe these alternate assessments as part of the statewide testing system, alongside the general assessments. ([cde.ca.gov](https://www.cde.ca.gov/TA/tg/ca/))

For English learners with significant cognitive disabilities, California also offers the Summative Alternate ELPAC. This helps ensure that the state's testing system includes students with diverse learning needs while still meeting federal and state assessment obligations.

Recent California Testing Updates That Matter in 2026

California's testing rules are not static. The CDE has issued recent updates that affect how schools administer and report assessments. For example, the CDE announced that, beginning with the 2026 Dashboard and future publications, grace periods were removed from the participation rate calculation for the ELA, mathematics, and science indicators. The same update says participation is now calculated using all students enrolled during the testing window. ([cde.ca.gov](https://www.cde.ca.gov/Ta/ac/cm/dashboardacad.asp))

The CDE also released a July 2026 letter updating screening requirements for risk of reading difficulties, showing that California continues to refine early identification and assessment practices. While this screening is separate from CAASPP and ELPAC, it reflects the broader direction of California education policy: earlier support, clearer testing rules, and stronger implementation guidance for districts. ([cde.ca.gov](https://www.cde.ca.gov/nr/el/le/yr26ltr0724.asp))

Another current detail is timing. The CDE's Assessment Spotlight notes that the 2026-27 interim assessments and related CAASPP and ELPAC components became available after system updates on August 4, 2026. That kind of calendar detail matters for districts planning test administration, training, and student support. ([cde.ca.gov](https://www.cde.ca.gov/ta/tg/sa/assessmentspotlight372.asp))

What Parents Should Expect

Parents in California should expect to receive notice from their school or district about required testing windows, student eligibility, and any accommodations or supports. Schools generally handle registration, scheduling, and test administration, but families may be asked to help ensure students attend on testing days. If a student is an English learner, parents should expect annual ELPAC testing until reclassification. If a student has an individualized education program, the school will determine whether the student takes the general assessment or an alternate assessment. ([cde.ca.gov](https://www.cde.ca.gov/sp/ml/elpacrequirmnts26.asp))

It is also wise for families to understand that California testing is tied to both student learning and school accountability. A student's test results may help teachers identify strengths and gaps, while schoolwide participation and performance can affect public reporting on the California School Dashboard.

Key Takeaways for California School Testing

• California uses a statewide testing system, not a single exam, to measure student learning and English proficiency. ([cde.ca.gov](https://www.cde.ca.gov/TA/tg/ca/))
• Most students in grades 3-8 and 11 take CAASPP assessments in English language arts and mathematics, with science testing also part of the system. ([cde.ca.gov](https://www.cde.ca.gov/Ta/ac/cm/dashboardacad.asp))
• English learners must take the ELPAC every year until they reclassify, and the annual summative window runs from February 1 to May 31. ([cde.ca.gov](https://www.cde.ca.gov/sp/ml/elpacrequirmnts26.asp))
• Students with significant cognitive disabilities may take alternate assessments instead of the general tests. ([cde.ca.gov](https://www.cde.ca.gov/TA/tg/ca/))
• California continues to update testing rules and accountability calculations, so districts and families should rely on current CDE guidance. ([cde.ca.gov](https://www.cde.ca.gov/Ta/ac/cm/dashboardacad.asp))

Final Thoughts

California school testing requirements in 2026 are best understood as a structured system built around student grade level, language status, and educational needs. For families, the most useful approach is to stay informed through the school district and the California Department of Education, especially because testing windows, participation rules, and accountability measures can change. The good news is that California provides a detailed framework intended to support student learning while also giving schools a clear picture of progress.
