🌱 Building Momentum — This label means the data doesn't clearly sort the school one way or the other — ask what the school is proud of, and what it's working on.
Most rating sites would stop at “60% proficient” and call it done. Rio Seco deserves a closer read. The school sits in Santee, where two in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.
Rio Seco's low-income kids hit 51.0% proficiency in ELA — a number the same group reaches at 38.2% statewide. If you're trying to read past zip-code-driven test scores, that's the signal worth weighing.
The seven-year arc
Has held the 73rd-percentile line every tested year since 2019.
This school hasn't fully recovered from the pandemic: 60% meet the standard today, versus 66% in 2019 — a gap worth asking about on a visit.

The story this school is actually telling
chronic absenteeism — versus 17.9% statewide. Attendance is the quietest strong signal a school can post.
math proficiency runs 60% in grade 3 against 50% in grade 5, while reading holds (58% to 61%). The state average rises by +4.5pp over the same span.
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 holds steady across grades; the floor rises 3.4pp. The state average rises 4.5pp over the same span. The school's 5th graders aren't posting a wider lead than its 3rd graders. One question worth asking on a tour: are the strongest students being pushed, or coasting? A school visit and conversation with teachers will tell you more than this number.
Rio Seco's most underrated number
