Third Grade · reading to learn, the first standardized test, grades that count
Third Grade in California
California public schools are overseen by the California Department of Education. This is the Third Grade view of one honest K-12 platform, from the state capital of Sacramento to the smallest district in between.
Schools across California
State capital
Sacramento
Schools statewide, from the capital to every district beyond it.
Serving schools in
Los Angeles, San Diego, San Jose, San Francisco, Fresno, and Sacramento
and the towns in between — the small schools, not only the big ones.
What Third Grade looks like here
The pivot from learning-to-read to reading-to-learn; the first year of state standardized testing in most states, and the first taste of academic independence.
Third grade is where a real gradebook-of-record starts to matter -- assignments, categories, and a term grade a parent watches; exact-integer weights, no float drift.
From the lower-elementary fluency grades into upper elementary; independence and the first testing arrive together.
Standards
The academic standards Third Grade follows in California
California adopts its own academic standards; the California Department of Education is the authority that sets what a public school teaches. Below are the real, currently listed California standards documents for Grades 3-5, by subject, with a link to each one so you can read it at the source. We write our own free Third Grade materials to align with them; we are not the California Department of Education, and we are not endorsed, approved by, or affiliated with it.

Standard codes and text are drawn from the Common Standards Project / Achievement Standards Network (ASN) corpus, republished by D2L Corporation (CC BY (per-document; see each cell.document.license)). 3rd-party aggregator copy, NOT an authoritative state publication. Verify against each document's own source before treating as authoritative. We do not present this as an authoritative crosswalk; each state agency’s own publication, linked above, is the authority.
Honest by default
The school stays the FERPA custodian of student records; a rep-scoped view reads zero grade rows at the database engine. Money, pricing, and checkout are honest-off on this page, and any school count above is an NCES Common Core of Data reference figure, never a claim of adoption in California.
Where these numbers come from
Data from the NCES Common Core of Data, 2023-2024. Schools may have opened or closed since publication.
