Summary
Alta Vista Elementary is a K–8 school serving 531 students in Porterville, California, near 10 other schools included in these comparisons. In 2025–2026, its all-grade proficiency was 18% in English Language Arts/Literacy (ELA), 9% in math and 10% in science. Results were low across grades and subjects: Alta Vista scored below every nearby school with same-grade data in ELA and in most grade-level math comparisons. Its most important challenge is that achievement is far below nearby schools and the state, particularly in math.
Science is Alta Vista’s relative bright spot: its 10% proficiency is above one nearby school’s result, though below the other nine, and its gap from the state is smaller than in ELA or math. Still, it trails California’s rates of 49% in ELA, 38% in math and 36% in science by 31, 29 and 26 percentage points, respectively. Compared with nearby-school averages of 41%, 37% and 22%, it is behind by 23, 27 and 11 points. Alta Vista’s student–teacher ratio of 20.8 in 2024–2025 was lower than all 10 nearby schools, whose ratios ranged from 22.3 to 25.5, but that did not coincide with stronger test results. The supplied district test figures duplicate the school’s, so they provide no separate district comparison.
Over the longer comparison from 2022–2023 to 2025–2026, ELA rose 2 percentage points, math fell 2 points and science rose 2 points; the state’s faster gains meant the gap widened by 6 points in math and 4 in science. SchoolDigger ranked Alta Vista at the 2nd percentile with 0 stars in 2025–2026, while nearby schools ranged from the 27th to the 68th percentile. The school reported 91% free/reduced lunch eligible in 2024–2025, close to the 90% average among eight nearby schools with the same measure; this is context, not an explanation for results. SchoolDigger’s English Language Learner subgroup ranking was notably higher than the school’s overall ranking: 21st percentile in 2023–2024 versus 5th overall, after reaching the 31st percentile in 2021–2022. That indicates comparatively stronger statewide standing for this group, although its percentile declined by 10 points from its earlier high.
