Benchmarked against the Bureau of Labor Statistics industry average of 4.5 for Other Urban Transit Systems, 422 Chicago Public Schools Il's workforce experiences 92% of the typical injury burden. This ratio matters because TCR already normalizes for hours worked — a 200,000-hour exposure base equals roughly 100 full-time workers — so establishments with very different headcounts can be compared directly. A TCR below the benchmark signals that controls, training, or automation may be outperforming peers.
Multi-year trend analysis is the single most reliable signal here: a one-year spike could reflect a single severe event, whereas sustained elevation across 2 reporting cycles points to systemic hazard exposure. Readers evaluating 422 Chicago Public Schools Il as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 0, and any year-over-year deterioration shown in the table below.

DART Rate — Transparent Calculation (2023)
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
0 DART incidents × 200,000 ÷ 123,612 hours worked = 0.00 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
