Educators and school personnel play a vital role in promoting well-being and identifying and responding to emerging mental illness in children and adolescents. However, they often have not received the training and ongoing support needed to respond in the classroom. To address this need, the MHTTC Network, in partnership with the National Center for School Mental Health (NCSMH) at the University of Maryland School of Medicine, developed a FREE 3-part training package focused on educator mental health literacy. Informed by and co-developed with K-12 educators, Classroom WISE (Well-Being Information and Strategies for Educators) launched in June 2021. Since then, over 10,000 educators and school staff have completed the training! This summary highlights participant feedback as well as MHTTC's dissemination and implementation efforts for Classroom WISE since its launch.
