RULER Training

RULER implementation begins with personal and professional learning for leaders and educators, and continues with classroom instruction for students and family engagement and education.

The RULER Training Institute is the first step to bringing RULER to a school. A small team from the school (one principal and two educators or mental health professionals) attends the institute, either in-person or online. Following training, the team who attends receives remote coaching and online resources to lead RULER implementation in their school community.
