Summary:
ZIP code 91306 has two middle schools serving grades 6–8: John A. Sutter Middle (763 students) and Ingenium Charter Middle (179 students); 2024–2025 is the latest year with all-grades results for both. The most important shared finding is that both schools were well below state proficiency levels in every subject that year: their average shortfalls were 26 percentage points in English language arts (ELA), 20 in math, and 22 in science.
Sutter is the local leader in all three comparable subjects, while Ingenium has the lower results. In 2024–2025, Sutter had 27% proficiency in ELA, 21% in math, and 14% in science, compared with Ingenium’s 17%, 13%, and 7%. Sutter’s advantages were 10 percentage points in ELA, 8 in math, and 7 in science. Even the stronger local results remain below the state: Sutter was 21 points below in ELA, 16 in math, and 19 in science.
Sutter’s latest results show declines in ELA and math but a modest science increase: from 2024–2025 to 2025–2026, proficiency fell 6 percentage points in ELA and 3 in math, while rising 2 in science. Its gap with the state widened in all three subjects. SchoolDigger lists Sutter at the 12th percentile with 1 star for 2025–2026; Ingenium’s latest listing is the 8th percentile with 0 stars for 2024–2025. As context, in 2024–2025, free/reduced lunch eligible (FRL) figures were 92% at Sutter and 97% at Ingenium; student–teacher ratios were 15.2 and 18.6, respectively. Ingenium has no 2025–2026 test results in the supplied data, so a same-year comparison is unavailable.
