Most Martinez addresses are in Martinez Unified School District, which runs four elementary schools, Martinez Junior High and Alhambra High. Some parts of town are in Mt. Diablo Unified instead, so the district, and the school, depends on the exact address.
Check that address with the district before you write an offer. A listing that says “Martinez schools” doesn’t settle it.
Which school districts cover Martinez?
Two. Martinez Unified School District (MUSD) has its office at 921 Susana Street and enrolled 3,787 students in 2025-26 (California School Dashboard, district profile, checked September 24, 2026). Mt. Diablo Unified School District (MDUSD), based in Concord, says its schools serve Clayton, Concord, Pleasant Hill, “portions of Martinez,” and other nearby areas (MDUSD, Schools page, checked September 24, 2026).
So the district line doesn’t match the city limit, and a Martinez mailing address alone won’t tell you which district you’re in.
How do I find the school for a specific address?
Use the district tools, then call to confirm.
- Martinez Unified. The district’s School Finder map is linked from its registration page at martinezusd.net. The registration page also lists the registrar contacts for elementary, Martinez Junior High and Alhambra High (MUSD, Registration page, checked September 24, 2026).
- Mt. Diablo Unified. MDUSD’s School Locator at schoolsitelocator.com/apps/mtdiablo returns the assigned schools for an address, and its School Feeder Pattern page shows which elementary feeds which middle and high school (MDUSD, checked September 24, 2026).
- Call the district office with the full address if the map puts a home near a line. Boundaries and transfer rules change, and the district’s answer is the one that counts.

How do the individual Martinez Unified schools compare?
They vary more than the district average shows. Test results from the 2025 Dashboard, in points above (+) or below (-) the state standard (California School Dashboard, checked September 24, 2026):
| School | English (points) | Math (points) | Chronic absenteeism |
|---|---|---|---|
| John Muir Elementary | -3.5 | -16.8 | 16.7% |
| John Swett Elementary | +26.7 | +11.6 | 9.1% |
| Las Juntas Elementary | -34.1 | -48.3 | 15.5% |
| Morello Park Elementary | +48.1 | +33.0 | 6.5% |
| Martinez Junior High | +15.5 | -22.5 | 8.0% |
| Alhambra High | -9.9 | -74.7 | not reported |
Alhambra High’s graduation rate was 97.1%, and 57.3% of its graduates were counted as prepared for college or career (same source). On the Dashboard, high school test results come from 11th graders, so one class can swing them.
These numbers are one year of one measure. They say nothing about a specific teacher, program or classroom. Visit, ask questions and read each school’s full Dashboard page before you decide how much weight to give them.
