Summary

Potrero Elementary in Potrero, California, serves 300 students in kindergarten through grade 6 and is part of Mountain Empire Unified. Its 2025–26 results show low proficiency in English language arts (ELA) and math, with science a relative strength. The clearest concern is ELA: 11% of students were proficient, the lowest result among nearby schools with results and 38 percentage points below the state.

Potrero trails both the state and district in all three subjects, and performs below the average of nearby K–6 schools in ELA and math. Its ELA result was 11%, compared with 26% districtwide and a 33% nearby-school average; in math, Potrero had 11%, versus 17% for the district and a 24% nearby average. The nearby comparisons include Clover Flat Elementary, Descanso Elementary and Campo Elementary. Science is the school’s relative bright spot: 13% proficiency was about level with the district’s 13% and above two of those three schools, but below the state’s 36% and Descanso’s 39%.

Over four years, Potrero’s proficiency rose 2 percentage points in ELA, 5 in math and 1 in science, but the state gap widened in ELA and science and narrowed only slightly in math. Chronic absenteeism improved from 53% in 2021–22 to 34% in 2025–26, though it remains above the district’s 20% and state’s 18%. SchoolDigger ranks Potrero in the 2nd percentile statewide, with 0 stars—the lowest standing among nearby schools with a reported rank. In 2024–25, its student–teacher ratio was 25, second-highest among nearby schools reporting a ratio, and 79% of students were free/reduced lunch eligible, the highest reported share among nearby schools using that measure. One relative subgroup finding: SchoolDigger placed the school’s effectiveness for English learner students at the 20th percentile in 2023–24, compared with its overall 2nd-percentile standing, though that subgroup ranking varied across earlier years.
