Summary:
Lodi School District has one middle school, Thomas Jefferson Middle School, serving grades 6–8 with 686 students. In 2025–2026, its unweighted average proficiency was 58% in English Language Arts (ELA) and 36% in mathematics, both above state averages of 53% and 34%. Most importantly, its ELA results were above the state in all three grades, though the grade 6 advantage was just 0.2 percentage points.
Within the school’s results, Algebra I is the standout strength: in 2025–2026, 100% were proficient on both the End-of-Course measure and the separate 8th-grade measure, compared with 40% and 75% statewide. The clearest weakness is 8th-grade science, where 13% were proficient versus 19% statewide—a gap of 6 points. Mathematics results also differ sharply by grade: the school was 6 points below the state in grade 6 and 8 points below in grade 7, but 20 points above in grade 8. Because this list includes only one school, it cannot show which school leads or trails within the district.
Results have shifted notably over time: the school’s average ELA proficiency fell from 79% in 2024–2025 to 58% in 2025–2026, and its advantage over the state narrowed from 22 points to 5; its mathematics average fell from 38% to 36%, while its state advantage narrowed from 5 points to 2. SchoolDigger’s ranking also fell from 209 of 752 schools (72nd percentile) in 2024–2025 to 313 of 743 (58th percentile) in 2025–2026. Context figures for 2024–2025 include a student-teacher ratio of 11.5, 66% eligible for free/reduced lunch, and chronic absenteeism of 11%, compared with 11% districtwide and 14% statewide.
