If students and teachers do not feel safe, it is difficult for learning to occur. But how safe do they really feel? And what do teachers think would improve that sense of safety? Is it another security camera, an additional active shooter drill? A social-emotional learning program? Resources for student mental health? What are schools doing now to make schools safer? In the eyes of teachers, how adequate are their efforts? In April of 2019, the Education Week Research Center set out to address such questions with an online survey of nearly 700 PreK-12 teachers. The objective of the survey was to examine the intersection between multiple factors with the potential to make schools safe. These factors include both "hardening" measures such as reinforced doors and armed teachers, as well as solutions related to students social-emotional skills and mental health.
