A survey of 12 medical and other health sciences schools which have implemented a standard three-year curriculum in the past few years revealed that only one of these schools is planning to revert to a standard four-year program. Some are introducing more attractive four-year curriculum options. The schools' self-ratings of the success of the three-year curriculum were generally favorable. Three- and four-year students were found to be comparable in cognitive knowledge and clinical skills, although comparison of three- and four-year students at one school showed that the four-year class rated itself far superior to the three-year class in knowledge. Faculties appeared to be somewhat dissatisfied with the three-year curriculum, but students enrolled in this program appeared generally favorable toward it. Overwork and overcrowding were cited as problems. Implementation of the three-year program provided the impetus for intensive preliminary review and reorganization of the educational program, a beneficial side effect. Because of apparent discrepancy between the schools' reported success with the three-year program and extreme caution in discussing it, as well as between reported success and general faculty dissatisfaction, clearer delineation of the impact of a three-year program is advocated.
