The verdict

Cosley Zoo runs at 202% of its industry's injury rate - far more dangerous than the typical Zoos workplace, earning a grade F.

Cosley Zoo: 6.3 TCR = 202% of Zoos BLS 3.1 · 8y Form 300A (see methodology below)

Cosley Zoo safety composite

Cosley Zoo scores strongest on total case rate (tcr) (safer than 52% of same-industry peers) and weakest on dart rate (safer than 11%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
