Summary
Deputy Superintendent Corinne presented the 2025 CAASPP and CAST results: district ELA results are steady, math improved slightly, science showed gains, participation met the 95% state target, and performance gaps by language, disability and socioeconomic status remain.
Deputy Superintendent Corinne Vidyoza presented Jefferson Union High School District’s California Assessment of Student Performance and Progress (CAASPP) and California Science Test (CAST) results for the 2025 testing cycle during the board meeting on Oct. 25, 2025.
Vidyoza said 57% of the district’s 11th graders met or exceeded standards in English Language Arts, and 33% met or exceeded standards in mathematics. She noted the district met the state participation target of 95%: "We also met the state target of 95% participation rate, which is a big accomplishment," Vidyoza said.
Across student groups, Vidyoza reported persistent gaps: English learners and students with individualized education programs (IEPs) performed below their peers in both ELA and math, and Hispanic/Latino students were generally below the district average. "Our English learners and students with IEPs are performing below their peers, and those gaps have remained fairly steady over time," she said.
School-level snapshots showed mixed results. Jefferson High School improved in both ELA and math by roughly five percentage points, Vidyoza said, and Westmore and Thornton reported math gains. Oceana continued to show the highest overall percentages in both subjects, while Terra Nova saw gains in ELA and math but a noted decline among Hispanic students in math that the district said warrants further review.
On science testing (CAST), Vidyoza reported gains districtwide and called science “the area where we’ve seen the most consistent improvement.” For alternate assessments administered to students with extensive support needs, 15% met or exceeded standards in both ELA and math; she noted the small cohort size (20 students) when presenting that result.
The district plans to support continued improvement with new instructional materials (CommonLit for ELA, OpenSciEd for science and an upcoming math pilot), benchmark assessments, classroom walkthroughs and targeted site goals. Vidyoza said principals, instructional coaches and district leaders are using benchmark and walk-through data to refine supports.
Trustees and student advisors asked for additional cross-dataset analysis: board members requested correlations between CAASPP results and A–G completion, AP participation/scores, and prior achievement in feeder districts. Vidyoza said the district will produce further comparisons on request.
No formal action was required at the meeting; the presentation concluded with a commitment to continue data-driven school support.
