Summary
El Dorado Elementary serves 766 students in kindergarten through grade 5 in Lancaster, within the Lancaster Elementary district. Its latest proficiency results are far below district and California levels, and it has high chronic absenteeism. The most important concern is that proficiency is low in all three tested subjects, with English language arts (ELA) the clearest weakness.
Compared with the state and district, El Dorado trails in ELA, math and science: in 2025–2026, proficiency was 12% in ELA, 10% in math and 10% in science, versus 49%, 38% and 36% statewide and 25%, 15% and 17% districtwide. That means it was about 37 points below the state and 13 below the district in ELA; the gaps were 29 and 6 points in math, and 26 and 7 in science. Among nearby K–5 schools with results, averages were 21% in ELA, 14% in math and 14% in science. El Dorado was below those averages by 9, 4 and 4 points. It ranked near the bottom locally in each subject: lowest in ELA except for Joshua Elementary, second-lowest in math and third-lowest in science.
Results have weakened since 2022–2023: ELA fell 8 points and math fell 8, while science was nearly flat, down less than 1 point; meanwhile, statewide results rose in all three subjects. Chronic absenteeism remains high at 45% in 2025–2026, compared with 32% in the district and 18% statewide, though it has improved from 56% in 2021–2022. SchoolDigger places El Dorado in the 1st statewide percentile, with zero stars, down from the 6th percentile in the prior two years. Its student-teacher ratio was 26.4 in 2024–2025, and 95% of students were free/reduced-lunch eligible that year, the highest share among nearby schools with comparable data. SchoolDigger’s measure of how well the school served English Language Learner Students fell from the 64th percentile in 2021–2022 to the 1st in 2023–2024; its measure for Homeless Students fell from the 25th percentile in 2024–2025 to the 2nd in 2025–2026.
