Simulation-based training provides realistic learning environments, allowing skill development without patient risks.1 Despite successful applications in gastroenterological procedures,2–4 implementing simulation-based training optimally remains challenging.1 Although research often emphasizes high-fidelity simulators and emerging technologies, a gap persists: the need for trainers. Trainers provide feedback, facilitating progression through a learning curve and toward competence.1,5,6 However, the availability of qualified instructors is often insufficient for training large cohorts, compromising training scalability.
