Pediatric graduate medical education (GME) is supported and enriched by a network of national organizations that provide resources, advocacy, guidance, and community to program directors, associate program directors, faculty educators, program administrators, and other administrative staff. Understanding the roles, contributions, and offerings of these organizations is essential for building successful, innovative residency programs that both meet accreditation standards and ensure certification of learners once residency is completed. This chapter briefly outlines the most critical pediatric organizations involved in medical education and why every leader in pediatric GME should be familiar with them. Many of these organizations offer important tools and curricula that can save time and effort for program leaders. With such rich collaboration in pediatric education, programs can build on shared resources rather than creating each program element from the ground up.
