Staff Development Administration safety composite

Staff Development Administration scores strongest on total case rate (tcr) (safer than 72% of same-industry peers) and weakest on dart rate (safer than 16%), 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).

Grade D

More dangerous than peersSafer than peers

Narrower to Connecticut alone (the establishments it most directly competes with for workers and contracts): ranked #77 safest of 381 Elementary and secondary schoo employers in Connecticut.

Staff Development Administration (55 employees, TCR 2.3) among 29 same-industry peers, split at the industry median of 76 employees and a TCR of 3.8

Staff Development Administration has fewer employees than the Elementary and secondary schools median and a lower injury rate than the industry's median TCR of 3.8. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
