Summary

Sumner Elementary is a K-6 public school serving 444 students in the high-performing Claremont Unified district, but it performs closer to the state average while its nearby district schools rank significantly higher.

Academically, Sumner's proficiency rates in English and Math are notably below the district average, creating a performance gap when compared to schools like Sycamore Elementary and Chaparral Elementary. A key challenge is chronic absenteeism, with a rate of 16.2% that is more than double that of most other Claremont elementary schools. Despite having the highest per-student spending in the district, this investment has not yet closed the academic gap with its peers. The school does show a particular strength, however, in its effective programs for special education students, who perform well above average.

Looking at trends, Sumner's statewide ranking has improved from pandemic lows but remains below its pre-pandemic standing. Performance also varies by grade, with a noticeable dip in 4th-grade scores. When compared to similar schools in other high-performing districts like Bonita Unified, such as J. Marion Roynon Elementary, which serve students with similar economic needs, Sumner's academic outcomes are lower, suggesting factors beyond economics are at play. Addressing attendance and understanding the grade-level performance swings appear to be central opportunities for the school's continued improvement.
