The Challenger Program for Residencies gives programs the ability to assign learning content for each of their rotations and to be able to pull documentation on the completion of these assignments. Many programs use this feature to create pretests and posttests for their rotations. Programs can either select from Challenger's standard rotation curriculum design, or can design a customized curriculum based on their program's specific needs. Content can be taken from various Challenger courses and from other internal or external resources.
