Summary

Northgate High serves 1,546 students in grades 9–12 in Walnut Creek, an East Bay community, and is part of the Mt. Diablo Unified district. The most important takeaway is that Northgate’s 2025–2026 test results were well above state and district levels in all three subjects: 83% in English language arts (ELA), 61% in math and 54% in science.

ELA is Northgate’s strongest subject compared with nearby comprehensive high schools, while science is its least advantaged relative to state and district benchmarks. Among six nearby schools with current results, Northgate ranked second in ELA and third in math and science; it trailed Acalanes High in ELA and math, and Monte Vista High and Acalanes in science. Northgate’s results exceeded the state by 34 percentage points in ELA, 23 in math and 18 in science; its advantages over the district were 34, 22 and 20 points, respectively. Completion outcomes were also strong: graduation was about 100%, compared with 94% districtwide and 88% statewide.

Scores are higher overall than in 2022–2023: math rose 7 percentage points, while ELA and science each rose 2. The path was uneven—ELA dipped before rebounding, and science’s lead over the state narrowed. SchoolDigger gives Northgate five stars and ranks it in the 92nd percentile statewide for 2025–2026; nearby Monte Vista and Acalanes rank slightly higher, at the 96th and 95th percentiles. Northgate’s 2024–2025 student–teacher ratio was 23.1, and 22% of students were free/reduced lunch eligible that year. SchoolDigger’s statewide ranking for Asian students was at the 73rd percentile in 2025–2026, up from the 56th percentile in 2023–2024, compared with the school’s overall 92nd-percentile rank. Its ranking for Multi-racial students was at the 75th percentile, down from the 87th percentile in 2023–2024.

Open Quote If you have a high performing child then you are in great shape. If you have a child in the middle ground or WORSE (IEP or 504) then you are in BIG trouble. My child had a 504 plan where the documented LD specified that she take tests in an environment other than the class room. Northgate said we do have the facilities to do this. She was not allowed in Resource, not allowed in the hall, not allowed in the library. They did enforce her 504 modifications with their teachers.

Why? Because they can't retain their teachers. My kids had NO spanish teacher, no algebra teacher etc. for more than the first 3 months. The AP and Honors classes ALways had teachers.

In 10 years we have had 3 principals and the entire Vice principal Staff left in 2014- 2015 and almost all.
