Marine Science Magnet School safety composite

Marine Science Magnet School scores strongest on total case rate (tcr) (safer than 86% of same-industry peers) and weakest on dart rate (safer than 24%), 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).

Marine Science Magnet School has fewer employees than the Elementary and Secondary Schools median and a lower injury rate than the industry's median TCR of 3.8.
