🌱 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 “23% proficient” and call it done. Mary B. Lewis deserves a closer read. The school sits in Bloomington, where four in five students qualify for free or reduced lunch — and reading the numbers without that context misreads the school.

Worth a school visit

Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.

  • Ask how the school follows up when a student starts missing days — chronic absence often starts outside the classroom, not inside it.
  • 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.
