Summary:
Chicago Public Schools District 299 includes 614 schools—456 elementary, 10 middle, 145 high and 3 alternative—serving students from elementary through high school across Chicago; in 2025–2026, district IAR proficiency was 46% in ELA and 29% in math, about 11 points below statewide results in each subject. The most important finding is how sharply results vary among the schools represented, from near-ceiling proficiency to very low scores.
Keller Elementary leads the elementary examples, with 99% ELA and 97% math on IAR All Grades—43 and 57 points above state results—and 100% proficiency in fifth-grade science; SchoolDigger ranks it first among elementary schools. Payton College Prep leads the listed high schools on 11th-grade ACT, with 96% ELA, 94% math and 95% science, beating state results by 46, 54 and 47 points; SchoolDigger ranks it third. At the lower end, Dulles had 11% ELA and 4% math, while Dett had 10% ELA. Englewood STEM recorded 5% ELA and 6% science on the ACT, 45 and 42 points below state results; its math score was suppressed.
In a matched four-school panel, average IAR ELA was essentially flat from 2024–2025 to 2025–2026—79.6% to 79.5%—while math fell from 69% to 67%; state results rose 3 points in ELA and 1 in math, so the panel’s gaps narrowed even without broad score gains. Context also does not neatly predict results: Healy reported 79% free/reduced lunch eligible (sy 2024–2025) and scored 70% in ELA and 64% in math, while Eberhart reported 94% eligible and scored 25% and 19%. SchoolDigger ranks the district 568th of 738, in the 23rd percentile, with 1 star; use rankings alongside school-level results, not as a substitute for them. The supplied records cover a selection of district schools, and results across different tests and grade spans are not directly comparable.
