Preliminary Testing Framework for K–12 Schools for the 2022–2023 School Year

This guidance is outdated and for historical purposes only. For current guidance, see Testing Framework for K–12 Schools for the 2022–2023 School Year web page.

​This document aims to inform California's K–12 schools of anticipated changes to COVID-19 testing strategies for the 2022–2023 school year  It is intended to support current and ongoing planning processes. 

Testing remains a key mitigation layer to detect and curb transmission of COVID-19 in school settings. To date, more than 78.3 million tests have been administered at schools, and nearly 32 million over-the-counter (OTC) tests have been distributed by state agencies to local school communities. 

The following list describes current and anticipated updates to COVID-19 testing operations for K–12 schools:

  • Currently, California is offering an additional 15 million COVID-19 OTC tests to all county offices of education (COEs) for use by public and private school students and staff during the end-of-year and summer school period. CDPH has communicated with COEs about this program, and COE distribution is well underway in most counties; for more information, please contact your local COE.

  • Starting August 1, 2022, CDPH will be able to offer more distributions of COVID-19 OTC tests to schools. Schools may use OTC tests to supplant on-site testing in many situations. Such efforts will be paired with ongoing statewide, school-focused educational materials to facilitate proper OTC use, particularly in communities with limited English proficiency and/or lower health literacy.

  • CDPH recommends that antigen tests be considered the primary option for detecting COVID-19 in schools, compared to PCR tests. Both the professional, on-site antigen tests as well as the OTC at-home antigen tests have been effective in identifying persons who have infectious levels of all known variants of SARS-CoV-2. PCR tests are highly sensitive, but their utility is greatest as a confirmatory test in appropriate situations, and/or in clinical settings. If you are currently participating in a CDPH school-based PCR testing program, please email for more information about transitioning to an antigen testing program in preparation for fall and to learn more about available resources.

  • CDPH will continue to support professional on-site antigen testing programs in the 2022-2023 school year. However, the volume of anticipated on-site testing is likely to decrease with the increased availability and ease of OTC tests. We anticipate the workload for on-site testing to substantially decrease for the 2022–2023 school year as OTC testing will often meet testing needs. Thus, state support for school-based testing staff (via End-to-End vendors and Personnel Grants) will be appropriately reduced. More information regarding these programs will be provided following enactment of the 2022–23 state budget.

These updates and anticipated changes are based on current scientific knowledge and anticipated trends. The framework is preliminary and subject to change. As noted in the SMARTER plan, and as we have all experienced, COVID-19 trends shift rapidly and California's response to conditions in schools must remain nimble, adaptive, and responsive to dynamic challenges.
