Summary
Anna A. Borba Fundamental Elementary serves 362 students in grades K–6 in Chino, California, near several other elementary schools. In 2025–2026, 33% of students met proficiency in English language arts (ELA), 25% in math, and 15% in science. The school’s results were below both California and Chino Valley Unified in all three subjects, and below the average of nearby schools with comparable grade spans—so its main challenge is low performance across subjects, not just in one area.
Relative to nearby K–6 schools, ELA is Anna A. Borba’s strongest subject: its 33% proficiency rate was below the peer average of 43%, but higher than one of the seven schools. In math, 25% was below the 34% peer average but higher than two schools; in science, 15% was below the 26% average and higher than one. Compared with California, the school’s gaps were 17 percentage points in ELA, 13 in math, and 21 in science. Compared with the district, the gaps were 31, 26, and 30 points, respectively. Chronic absenteeism has improved substantially, falling from 44% in 2021–2022 to 17% in 2025–2026, though it remains above the district’s 14%.
Results have weakened in ELA and math since 2022–2023: ELA fell 7 percentage points to 33%, while math fell 2 points to 25%. Science rose 10 points over that period to 15%, but declined from its 34% peak in 2023–2024. SchoolDigger’s overall rating fell from the 51st percentile and 3 stars in 2023–2024 to the 25th percentile and 1 star in 2025–2026. Context includes a student-teacher ratio of 21 to 1 in 2024–2025, the second-lowest among ten nearby schools, and a 89% free/reduced lunch eligible rate that year, above the same-district peer average of 85%. SchoolDigger’s subgroup rankings show higher standing for Homeless Students (67th percentile in 2025–2026 versus 25th overall) and, historically, English Language Learner Students (77th percentile in 2023–2024 versus 51st overall); the latter is not a current comparison, and the homeless-student ranking covers a smaller comparison pool.
