Summary:
Zip code 61943 has one listed elementary school, Lake Crest Elementary School, serving prekindergarten through eighth grade in Oakland CUSD 5. Because it is the only school in the list, there is no local school-to-school comparison. The most important finding is that its 2025–26 all-grades test results were below state results in both subjects, with the largest gap in math: 21% of students were proficient, compared with 40% statewide, a 19-point difference.
Lake Crest is both the highest- and lowest-scoring school in this one-school list, so that distinction is not a comparison with other local schools. Against the state, its all-grades ELA result was 42% versus 56%, 14 points lower; its eighth-grade science result was 41% versus 52%, 11 points lower. ELA was the stronger of its two all-grades subjects. The grade-specific ELA results were closer to state figures but remained lower: seventh grade was 53% versus 58%, and eighth grade was 56% versus 63%.
Results improved in ELA and eighth-grade science from 2024–25 to 2025–26, while math changed little. ELA rose from 30% to 42%, narrowing its gap with the state by 8 points; eighth-grade science increased from 29% to 41%, narrowing its gap by 6 points. Math edged up from 20.5% to 21.0%, while its state gap widened by 1 point. SchoolDigger’s ranking also weakened in its latest reported year: the school moved from the 38th percentile in 2023–24 to the 19th percentile in 2024–25, after ranking in the 27th percentile in 2022–23. Separately, reported chronic absenteeism was 14% in 2025–26, below the district’s 21% and the state’s 24%. In 2024–25, the school enrolled 185 students, had a 9.7:1 student–teacher ratio, and 47% were free/reduced lunch eligible. These are context measures, not evidence of what causes school results; with just one school, the data cannot establish an area-wide pattern.
