The verdict

Iowa DOT - Accounting runs at 61% of its industry's injury rate - safer than the typical Government - Transportation workplace, earning a grade B.

Iowa DOT - Accounting: 1.9 TCR = 61% of Government - Transportation BLS 3.2 · 4y Form 300A (see methodology below)

Iowa DOT - Accounting safety composite

Iowa DOT - Accounting scores strongest on total case rate (tcr) (safer than 64% of same-industry peers) and weakest on dart rate (safer than 53%), 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).
