The verdict

Arizona Proving Ground runs at 190% of its industry's injury rate - more dangerous than the typical Automobile Testing workplace, earning a grade D.

Arizona Proving Ground: 0.9 TCR = 190% of Automobile Testing BLS 0.5 · 4y Form 300A (see methodology below)

Arizona Proving Ground safety composite

Arizona Proving Ground scores strongest on total case rate (tcr) (safer than 53% of same-industry peers) and weakest on dart rate (safer than 29%), 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).
