Purpose The Interdisciplinary Leadership Learning Collaborative (ILLC), under the sponsorship of AUCD and the Maternal and Child Health Bureau, brought together six teams, composed of 14 MCHB and UCEDD training programs to enhance their leadership training. Description Using adult learning principles, interactive training methods, and skill-focused learning, the ILLC built upon the evidence-based Interdisciplinary Leadership Development Program of the University of North Carolina at Chapel Hill. The program began with a 4-day on-site intensive and then continued through monthly conference calls, a mid-term on-site workshop, and a summary virtual workshop to present programmatic accomplishments and share plans for sustainability. Coaching/consultation for the teams around particular challenges was also part of the program. Assessment All teams reported enhancements in intentional leadership training, threading of leadership concepts across clinical, didactic, and workshop settings, and new collaborative partnerships for leadership training. Teams also identified a number of strategies to increase sustainability of their intentional leadership training efforts. Conclusion for Practice The learning collaborative is a productive model to address the growing need for interdisciplinary MCH leaders.
