Summary

Diamond Technology Institute is a small high school serving grades 9–12 in Watsonville, within Pajaro Valley Unified; it has 87 students. Its latest academic results are mixed: ELA is exceptional, math is below the state, and science is near the state average after a steep recent fall. Most strikingly, 100% of students graduated in 2025–2026, compared with 93% in the district and 88% statewide.

ELA is Diamond’s clearest strength: 77% were proficient in 2025–2026, compared with 49% statewide and 28% in the district. That result was higher than all eight nearby high schools with reported scores and 34 points above their 44% average. Math is weaker relative to California: 23% were proficient, 16 points below the state, although that was above the district’s 18% and nearby schools’ 17% average. Only Aptos High and Soquel High scored higher among those peers. Science proficiency was 36%, about level with the state and above the district’s 19%; among seven nearby schools with reported results, Diamond ranked second, behind Soquel.

Results have shifted over time: from 2022–2023 to 2025–2026, ELA slipped 3 points, math fell 17 points despite a recent rebound, and science declined 9 points overall, including a 30-point drop in the latest year. SchoolDigger gives Diamond 3 stars and a 66th-percentile rating in 2025–2026, down from the 90th percentile in 2022–2023; its latest rank is 732 of 2,137 schools. In 2024–2025, the student-teacher ratio was 17 students per teacher, and 77% were free/reduced lunch eligible. SchoolDigger’s statewide percentile for Low Socio Economic Status Students, a measure of how well the school serves that group, fell from the 91st percentile in 2023–2024 to the 64th in 2025–2026. With 87 students, year-to-year test results can be sensitive to the number of students tested.
