Endoscopy training has evolved in recent years from the traditional model of "learning by doing" to the current skillful application of evidence-based educational principles. Endoscopy training should ideally be provided by individuals with the requisite skills and behaviors to teach endoscopy effectively and efficiently, including an awareness of principles of adult education, best practices in procedural skills education, and appropriate use of beneficial educational strategies such as feedback. The aim of this article is to outline principles that underlie successful endoscopy training and describe the "Preparation-Training-Wrap-up" framework that can be used by pediatric endoscopy trainers to help guide an effective endoscopy training session. Looking to the future, application of content from well-developed "train the trainer" courses to pediatric endoscopy practice would help to improve the quality of endoscopy training and facilitate the development of conscious competences among pediatric endoscopy trainers.
