Summary

Del Mar Middle is a highly-ranked public school serving 359 students in grades 6-8 in the affluent community of Tiburon, part of the top-performing Reed Union Elementary district.

Academically, Del Mar stands out as one of the best middle schools in California, consistently ranking in the top 2-3% of the state. Its students achieve proficiency rates well above state averages, with over 83% proficient in English and over 81% in Math. The school is particularly effective in supporting all learners, with exceptional results for students with special needs, ranking in the 97th-99th percentile for these subgroups. Key advantages include a very low student-teacher ratio of 11.6:1 and high per-student spending, which contribute to its focused learning environment.

When compared to nearby schools, Del Mar's performance is part of a cluster of excellent schools in Marin County, including Mill Valley Middle, Hall Middle, and Adaline E. Kent Middle. It significantly outperforms many schools in San Francisco and Richmond in academic proficiency. For instance, its math proficiency is over 50 percentage points higher than James B. Davidson Middle in San Rafael. This highlights a notable disparity in educational outcomes across the Bay Area, often linked to strong district support and resources.
