About Schools in San Dimas, California
San Dimas, California offers parents a compact but high-performing public school landscape. The city has 14 ranked public schools spanning elementary through high school, with an average score of 7.3 out of 10 across the full set. That average is the headline: 11 of those 14 schools — 79% — score 7 or higher, meaning strong options are the rule here, not the exception.
At the top sits San Dimas High, the city's highest-rated school at 8.5 out of 10. It leads a strong secondary tier: Bonita High follows closely at 8.2, giving families two competitive high school options with scores well above the citywide average. Parents of younger children will find similar consistency at the elementary level. Fred Ekstrand Elementary scores 8.0, while both Grace Miller Elementary and J. Marion Roynon Elementary each earn 7.8. All five top-rated schools clear 7.5 — a sign that academic performance holds up across grade levels, not just at the high school end.
The practical implication for parents: San Dimas is a city where school quality rarely drops off sharply. With 79% of ranked schools scoring 7 or above, families moving into most neighborhoods here are unlikely to find themselves in a weak attendance zone. That said, the three schools that fall below the 7.0 threshold are worth examining individually — the 7.3 average means the lower end of the distribution does pull the number down, and boundary lines matter.
For families prioritizing academic performance at every stage, the strongest path through the system runs from Ekstrand, Grace Miller, or Roynon at the elementary level through to San Dimas High or Bonita High. The continuity from elementary to secondary is one of San Dimas's clearest assets. Parents should verify their address-based attendance zones early, confirm whether open enrollment or intradistrict transfers are available through the Bonita Unified School District, and cross-reference each school's test score data and demographic fit alongside these ratings before finalizing a decision.
