In 1989, a survey was sent to each U.S. and Canadian medical school requesting information about how standardized patients are used for teaching and evaluating clinical skills, and 95% of the schools responded. Although there was widespread use of standardized patients throughout the curricula, the role and training of these patients varied markedly within a given school as well as across schools. One outcome of this survey is the development of a network to share resources, protocols, and training material to enhance the development of this educational strategy.
