Child sexual abuse (CSA) in schools and educator misconduct represents a threat to the safety and well-being of our children. The Enough! Preventing Child Sexual Abuse in My School program is a 1-hour online training course developed to address the problem of sexual misconduct and CSA in K-12 education via the use of two avatars/teachers who are navigating CSA and misconduct in their schools. One hundred and thirty-four teachers from three school districts participated in a study to examine the effectiveness of the program in terms of knowledge awareness, including prevalence rates, types of CSA behaviors, impact of CSA on children, signs and symptoms, reporting responsibilities and responses to suspected abuse. Participants were randomly assigned to intervention and control groups: the intervention group (A) received the Enough! training and completed a pre-/posttest and an evaluation of the training (n = 61), Group B (control) completed the posttest only (n = 55), and Group C (control) completed both the pre- and posttests (n = 18). Results indicated that the intervention group's knowledge was significantly higher than that of the control group's at posttest. Group A participants reported a high level of satisfaction in the training, as well as increased knowledge, awareness and willingness to take action in the future. This study points to the need to further test the effectiveness of the Enough! program (and programs like it) on a wider-basis in an effort for educators to be better prepared to protect from the threat of CSA and sexual misconduct.
