Summary:
Lodi Unified has six middle schools: five serve grades 7–8, while Elkhorn serves grades 4–8. In 2025–2026, the five grade-7–8 schools averaged 34% proficiency in English Language Arts, 26% in math, and 19% in science—15, 12, and 17 percentage points below state results. Elkhorn’s results are the defining standout in this group.
Elkhorn led all six schools in all-grades ELA, math, and science, with 95%, 89%, and 87% proficiency, and ranked 5th of 2,703 statewide in SchoolDigger’s 2025–2026 rankings. Its lead over the next-highest school was 56 points in ELA, 56 in math, and 62 in science. Among the five schools serving grades 7–8, Millswood led in ELA and math, while Christa McAuliffe led in science. Delta Sierra had the lowest results in all three subjects among those five, at 25% in ELA, 15% in math, and 9% in science; SchoolDigger ranked it 2,438th statewide. Elkhorn’s broader grade span means its all-grades results are not directly comparable to the other schools, though it also led in same-grade comparisons.
Recent changes were mixed: from 2024–2025 to 2025–2026, the five-school average fell 2 points in ELA and rose 2 points each in math and science. The state-relative gap widened in ELA and science, while math’s narrowed slightly. Within the group, Millswood improved 5 points in math, while Lodi Middle fell 6 points in ELA. SchoolDigger’s rank history shows Christa McAuliffe moving from the 52nd to the 44th percentile and Lodi from the 40th to the 28th; Elkhorn stayed at the 100th percentile. Context figures also vary: for 2024–2025, free/reduced lunch eligible ranged from 45% at Elkhorn to 93% at Delta Sierra, while student-teacher ratios ranged from 18.5 to 25.8. Christa McAuliffe’s reported chronic absenteeism was 90%, versus 24% for the district and 18% for the state, despite its strong science results among the five grade-7–8 schools.
