Jefferson Middle

Jefferson Middle serves 959 students in grades 6 through 8 in San Gabriel, California. The school earns a composite score of 9.0/10 — rated Exceptional — with an academic score of 9.0 and a growth score of 9.3. A student-teacher ratio of 18.8:1 keeps class sizes moderate through the years when teacher-student relationships carry the most weight.

The statewide numbers are hard to ignore. Jefferson ranks #17 of 1,349 middle schools in California and outperforms 98% of all California public schools — a standard that holds across grade levels, not just within its own peer group. It also stands #1 among the 11 schools in San Gabriel, making it the clear academic leader in its immediate community.

Growth is the metric that sharpens the picture. At 9.3, Jefferson's growth score edges ahead of its already-high 9.0 academic score — a gap that signals the school is actively accelerating students, not simply serving those who arrive well-prepared. Families comparing middle school options in the San Gabriel Valley will find few schools that combine this level of achievement with this level of demonstrated progress.
