In response to persistent low math performance (Orange/Red on the Dashboard), Trinity High School is changing its math course progression back to a historical sequence beginning in 2026‑27: Math 1/Algebra in grade 9, Math 2/Geometry in grade 10, and Algebra 2/advanced courses in upper grades. The SPSA notes that prior sequencing (Geometry then Algebra) did not improve outcomes and that new math staffing arrangements and supports from the Trinity County Office of Education will be implemented for 2026‑27. The plan also states that new math curriculum is being explored for 2026‑27 based on new state adoption requirements and that the school is piloting math curriculum with county support.This is a clear early‑stage adoption cycle where vendors of state‑adopted or compliant high school math programs—print, digital, or blended—can influence selection by demonstrating alignment to California standards, CAASPP performance gains, and suitability for small rural high schools with intervention needs.

Math is an identified area of significant need, especially for socioeconomically disadvantaged and White student subgroups; the school also runs math intervention classes and after‑school tutoring.
