Summary

Mariposa Elementary is a K-6 public school serving 537 students in the Ontario-Montclair School District, operating in a high-need community where nearly 95% of students qualify for free or reduced-price lunch.

While the school's overall academic performance, as measured by state test scores, is below district and state averages and ranks in the lower statewide percentiles, it demonstrates remarkable strengths in specific areas. Most notably, Mariposa has achieved a dramatic and impressive reduction in chronic absenteeism, now at just 6.0%, which is better than both the district and state averages. Furthermore, the school shows exceptional effectiveness with some of its most vulnerable students, earning 4-star state ratings for its English Language Learner and homeless student subgroups, performing in the 74th and 84th percentiles respectively.

Comparisons with nearby schools reveal interesting contrasts; for instance, while Edison Elementary ranks much higher overall, the Online Academy serves a similar high-need population with stronger academic results, suggesting different educational approaches. The school's performance has been volatile year-to-year, but its recent success in boosting attendance and supporting specific subgroups suggests it may have foundational strategies that could lead to broader academic improvement in the future.
