Introduction: Two pioneering studies in Spain are presented on the Learning to Forgive program inspired by the research of Robert Enright and his team, pioneers in the education of forgiveness. Study 1 aims to analyze whether teacher training in the Learning to Forgive Program increases their knowledge of forgiveness and Study 2 evaluates the satisfaction of the program for teenagers. Method: In Study 1, the sample consisted of 88 primary and secondary school teachers, distributed in an experimental group (n = 63) and a control group (n = 25), belonging to 11 educational centers, and in Study 2 the sample consisted of 153 students belonging to 4 educational centers. Results: In Study 1, statistically significant improvements were found in the forgiveness group regarding their knowledge of forgiveness and marginally significant in emotional forgiveness compared to the control group. In Study 2 participants noted, among other data, high satisfaction with the program and that it had helped them forgive in a remarkable way. Discussion and Conclusion: In line with other studies, it is recommended to incorporate education in forgiveness into bullying prevention programs.
