Approach and Methods: The investigators will follow an organizational participatory research approach, and propose a cluster randomized controlled trial. Setting: All incoming family medicine residents in Canada will be eligible to participate. Intervention site residents will receive alerts through an app to adaptively reinforce the learning of clinical content based on cases and test questions (spaced education). Residents in the control group will receive the same app providing identical clinical cases and test questions-on-demand, but with alerts inactivated (no spaced education). The primary outcome will be scores on the certification examination. This routinely collected data will be provided to the team by the College of Family Physicians of Canada.
