The verdict

Middle School runs at 289% of its industry's injury rate - far more dangerous than the typical K-12 Education workplace, earning a grade F.

Middle School: 4.0 TCR = 289% of K-12 Education BLS 1.4 · 6y Form 300A (see methodology below)

Middle School safety composite

Middle School scores strongest on dart rate (safer than 79% of same-industry peers) and weakest on total case rate (tcr) (safer than 46%), 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).

Where Middle School falls in its industry

3,374 K-12 Education establishments

Safer than 46% of graded establishments in this industry, whose median TCR is 3.8.

Grade F

More dangerous than peersSafer than peers

Narrower to Minnesota alone (the establishments it most directly competes with for workers and contracts): ranked #893 safest of 1589 K-12 Education employers in Minnesota.

Middle School (66 employees, TCR 4.0) among 29 same-industry peers, split at the industry median of 76 employees and a TCR of 3.8

Middle School has fewer employees than the K-12 Education median and a higher 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.
