Middle Schools in Lincoln Unified

Lincoln Unified has one listed middle school: Sierra Middle, serving grades 7–8 and enrolling 591 students. With just one school, the figures describe Sierra rather than a range of local options. The most important finding is a split by subject: in 2025–2026, Sierra was ahead of California in all-grades English Language Arts/Literacy (ELA), but behind in math and science.

There is no meaningful local top-to-bottom comparison because Sierra is the only school listed; against the state, its clearest strength was grade 8 ELA, at 55% proficient compared with 49% statewide, a 5-point lead. Across all grades, ELA was 51% versus 49%, 2 points higher. The main shortfall was science: 29% were proficient versus 36% statewide, a 7-point gap. Math was also below the state, at 35% versus 38%, a 4-point gap. Grade 7 ELA was below the state (48% versus 51%), while math was below in both grades: 36% versus 38% in grade 7 and 33% versus 36% in grade 8.

Math and science improved substantially from 2024–2025 to 2025–2026: Sierra’s scores rose 6 points in math and 9 in science, while ELA slipped 1 point. SchoolDigger rates Sierra at the 58th percentile, with 3 stars, ranking it 1,135 of 2,703 schools in 2025–2026; its percentile was 56th in 2023–2024 and 55th in 2024–2025. Context measures include a 21:1 student-teacher ratio in 2024–2025 and 72% free/reduced lunch eligible that school year. Chronic absenteeism was 22% in 2025–2026, compared with 24% in the district and 18% statewide.
