🌱 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 “47% proficient” and call it done. Jefferson deserves a closer read. The school sits in Lennox, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

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 holds steady across grades; the floor rises 6.0pp. The state average rises 4.5pp over the same span. A school visit and conversation with teachers will tell you more than this number.
The 6 things our score weighs
Ask how the school challenges kids who clear the standard early. The gap between meeting and exceeding is where pacing shows.
- Ask what changes between grade 3 and grade 5 here, and who teaches the older kids.
- 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.
