Corte Madera: High scores, real growth, strong attendance. We looked for a catch — we didn't find one.
Corte Madera posts 60.7% exceeding the standard — versus 16.8% statewide — with climate numbers better than most. That doesn't make it perfect. It makes it worth a visit to find what numbers can't measure.

⭐ High Ceiling — Ask what happens for a kid who shows up behind — a high ceiling for the top can sit right next to thin support at the bottom, and the score alone won't show you which.
Most rating sites would stop at “86% proficient” and call it done. Corte Madera deserves a closer read. It sits at the 99th percentile of 2,238 California middle schools — but the ranking is the least interesting thing on this page.
The headline number: 60.7% of students scored in the top band on the state test. The California average is 16.8%.

The story this school is actually telling
The school, grade by grade
ELA · CAASPP 2024–25Different students, same year — each bar is one grade's proficiency mix.
The honest read: the share exceeding rises 17.5pp across grades; the floor rises 4.4pp. The state average falls 0.5pp over the same span. Kids here gain ground the longer they stay — the pattern you want to see. A school visit and conversation with teachers will tell you more than this number.
The 5 things our score weighs
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask how teachers track each child's growth over the year, not just where the class lands on test day.
- Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
- Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
- Ask how the school communicates with families when a child starts to struggle.
- Ask what a typical day looks like for a new student in the first few weeks.
