Martinez Unified School District (MUSD) serves almost all of Martinez — about 3,800 students across 9 schools (4 elementary, 1 middle, 1 high, plus alternative/adult). Much smaller than neighboring Mt. Diablo Unified, which shapes the district's character.
MUSD's smaller size means faster decision-making, more parent engagement, and a less bureaucratic feel than MDUSD. Some families specifically prefer MUSD for this — easier to know your kid's teacher, principal, and district leadership.
The main schools: John Swett, Las Juntas, John Muir, and Morello Park Elementary; Martinez Junior High; Alhambra High. Alhambra is the district's flagship public high school with solid academic and athletic programs.
Honest assessment: MUSD test scores sit around the regional middle — not a standout like WCSD, but above-average nationally. The culture and community tend to be the bigger attraction than raw academic rankings.
