This oral focus session will tell the story of implementing TBL™ in a multi-site, statewide training program serving the public child welfare workforce in the United States. Background: The Pennsylvania Child Welfare Resource Center (CWRC) at the University of Pittsburgh, School of Social Work serves the public child welfare system in Pennsylvania by designing and delivering training, transfer of learning, research and evaluation, and other services.  The CWRC partners with state government (the Office of Children Youth and Families), 67 local government (county) child welfare agencies, and many contracted instructors who deliver training curricula to thousands of child welfare professionals each year.  In 2018, the CWRC committed to the adoption of TBL™ as its primary teaching and learning method. The first CWRC training series selected for revision was the state mandated certification training series for newly hired public child welfare professionals with approximately 750-1000 enrolled annually. The 124-hour series, Foundations of Pennsylvania Child Welfare Practice: Building Competence, Confidence, and Compassion, (Foundations), was developed and piloted in late 2018 and early 2019, and fully launched statewide in July 2019. Implementation of TBL™: This session will tell the story of how CWRC implemented  TBL™ statewide into a child welfare training environment by convincing their stakeholders of the advantages of the TBL™, incorporating TBL™ design in its curriculum development processes, re-training over eighty new and existing instructors on TBL™ facilitation methods, and changing the culture and structure of curriculum delivery to its stakeholders. The successes and challenges that CWRC experienced throughout this endeavor will serve as an example for any organization or institution seeking to incorporate TBL™ in a training environment. The activities of the Pennsylvania Child Welfare Resource Center are made possible through grant funds from the Pennsylvania Department of Human Services to the University of Pittsburgh. Presenters are not students.
