Summary

Sierra Elementary is a K–5 school serving 707 students in Lancaster, California, and is part of the Lancaster Elementary district. Its 2025–26 proficiency was below the district and state in English language arts (ELA), math and science; most urgently, chronic absenteeism remains high at 39%, compared with 32% districtwide and 18% statewide.

Sierra’s all-grades results were low compared with both the state and nearby schools. In 2025–26, 16% of students were proficient in ELA, 11% in math and 9% in science; state rates were 49%, 38% and 36%, respectively. Sierra was also below the district by 9 points in ELA, 5 in math and 8 in science. Among eight nearby schools with results that year, averages were 25% in ELA, 17% in math and 17% in science, leaving Sierra 9, 6 and 8 points below those averages. Grade 4 was a particular soft spot: Sierra’s ELA proficiency was 14% and math proficiency 9%, and only El Dorado Elementary had lower Grade 4 ELA results among the nearby schools with data; only Joshua Elementary had lower Grade 4 math results.

Results have varied, but the longer-term comparison shows wider gaps with the state in all three subjects: from 2022–23 to 2025–26, Sierra’s science proficiency fell from 16% to 9%, and its science gap to the state widened by 13 points. Attendance has improved, falling 20 points from 58% in 2021–22, but remains a concern; only Joshua and El Dorado had higher rates among nine nearby schools with data. SchoolDigger placed Sierra at the 2nd percentile with 0 stars in 2025–26, up from the 7th percentile in 2021–22. In 2024–25, 93% of students were free/reduced lunch eligible, the second-highest reported share among ten nearby schools; the student-teacher ratio was 23.5. SchoolDigger’s subgroup rankings show a striking change for homeless students: the school’s standing for how well it serves this group rose from the 3rd percentile in 2022–23 to the 77th in 2024–25, while its overall standing was at the 5th percentile in 2024–25. For English language learner students, the subgroup percentile fell from 68 in 2022–23 to 10 in 2023–24.
