UChicago 5Essentials levels from the spring 2024 survey (CPS Progress Reports SY2425, verified 2026-09-25) - benchmarked categories relative to Illinois statewide, spring 2013, not percentages. A school can answer mostly positively and still rate below the benchmark typical.
5Essentials - the latest survey in detail
Reflective Dialogue, Collective Responsibility, and Innovation are rated above the CPS average; Inquiry-Based Science Instruction, Rigorous Study Habits, and Course Clarity are rated below it this year.
From the 2026 CPS 5Essentials survey (25-26). Scores are benchmarked 1–99 (not percentages) - higher is stronger, and each is shown against the CPS average that same year. This is a newer survey on a different benchmark than the component levels above, so the two aren’t directly comparable.
