U-Shaped Per-Pupil Equity Gap
Schools in the 60-75% FRPL range receive the least per pupil (~$17K), while both lowest- and highest-need schools receive more (~$21K and ~$22K). Middle-need schools are squeezed. (86% FRPL, CSI) receives just $14,728 per pupil.
New York's Foundation Aid formula, and the broader weighted-student-funding literature (e.g., Edunomics Lab, The Education Trust), treat poverty as a positive funding weight: high-FRPL schools should receive more per pupil, not less. The U-shape inverts that for the middle of the FRPL distribution.
