Punching above expectationFull briefing

Top-decile elementary scores from non-elite schools: 5 case studies

The longer form of the briefing for this story: the original thesis, the supporting findings the data team flagged, and the reporting directions a journalist could follow. For the short version and the data analysis, see the main story page.

Thesis

Most schools posting 90%+ elementary academic composite serve proclivity-decile-1 populations (G&T schools, wealthy zoned). But a handful hit the top decile from proclivity 5-7 (mid-pack student bodies). Profile 5 of these schools — what are they doing that the 'expected high performers' do?

Supporting findings

  • Schools in proclivity 5-7 hitting top citywide decile on composite_es_academic (2024-25):
  • (pull from /ratings/outliers?proclivity=5-7&direction=top)
  • Likely candidates: PS 188 The Island School (LES), PS 192 Magnet (Bronx), PS 33 Chelsea Prep (transition zone)
  • Mid-proclivity schools have less obvious resource advantages — what's their playbook?
  • Are they specifically dual-language? Anti-bias? Project-based? G&T-within-school?
  • Are they protected by specific demographic in-flows (e.g., Asian families in Sunset Park magnets)?
  • Compare with mid-proclivity schools NOT in the top decile — what's missing?
  • Look at five-year trajectory — did they always punch above, or did they climb?
  • What's the principal's tenure + background?
  • Cross-reference with InsideSchools narratives (private but tagged in our DB).
  • The pattern across these schools is the headline story.

Reporting directions

  • Pull the actual list (5-10 schools) from the outliers page.
  • Visit 3 in person, observe a math + ELA block at each.
  • Interview the principals — ask about specific practices.
  • Compare with the work of David Levin (KIPP cofounder) on what mid-tier schools can do.
