Summary

This study tested a program called Link for Equity, which trains school staff in trauma-informed care and cultural humility. The goal was to reduce racial/ethnic disparities in school violence and discipline. Over 1,600 staff from 12 Minnesota schools participated, with some receiving training immediately and others after a wait period. The study measured changes in staff attitudes about racism, microaggressions, and trauma-informed care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Behavioral intervention: trauma-informed care and cultural humility training for school staff
What this could lead to
If successful, this program could help reduce racial/ethnic disparities in school discipline and violence.
What could go wrong
This is a completed study measuring changes in staff attitudes, not direct violence outcomes. Results may not generalize to other schools or reduce actual violence.
