SchoolDigger Rank ?

of 5,817 California Elementary Schools

Better than 13% of California elementary schools

Summary

Blackford Elementary is a San Jose school serving kindergarten through fifth grade, with 414 students; its results can be compared with 10 nearby schools. In 2025–2026, 24% of students were proficient in English language arts (ELA), 23% in math and 10% in science. The clearest concern is that Blackford had the lowest all-grade proficiency rate among the 10 nearby schools in all three subjects.

Math is Blackford’s strongest subject relative to comparison schools, but it still trails each benchmark: its 23% proficiency rate is 15 points below California, 23 points below the Campbell Union district and 23 points below the nearby-school average of 47%. ELA is 24%, compared with 49% statewide, 52% in the district and a nearby average of 51%; those gaps are 25, 28 and 27 points. Science is weakest at 10%, versus 36% statewide, 46% in the district and a nearby average of 40%—gaps of 26, 35 and 30 points. Fifth-grade ELA is a particular concern: 19% were proficient, 30 points below the state rate, and this was the lowest fifth-grade result among nearby schools.

Over four years, ELA slipped by 1 point, math rose by 3 points and science rose by 2 points overall, though science has fallen 3 points from its 2023–2024 high. SchoolDigger ranks Blackford in the 13th percentile statewide and gives it 1 star in 2025–2026, up slightly from the 11th percentile the year before; the district is at the 64th percentile with 3 stars. Chronic absenteeism is also elevated at 21%, compared with 11% in the district and 18% statewide. Blackford’s student-teacher ratio is 21.7, below the nearby-school average of 23.1. Its reported low-income measure was 57% free/reduced lunch eligible in 2024–2025. One subgroup trend stands out: SchoolDigger’s Female Students ranking fell from the 28th percentile in 2023–2024 to the 8th in 2024–2025, then rose to the 12th in 2025–2026—a 16-point drop from its earlier standing.
