SummaryThe development and utilization of multiple‐choice test items and the utilization of computer technology have significantly altered evaluation practices in medical schools. This paper describes the development and implementation of a computer‐based multiple‐choice test item‐bank for use in a junior medicine clerkship. The computer program, ITEMBANK, is an interactive system that stores and edits test items and constructs and prints an original copy of each test. Tests can be produced almost immediately by the clerical staff and the total developmental costs have been minimal. The program has reduced the amount of teaching time required to develop tests, and has enhanced the learning of essential information by medical students and residents. Teaching staff and student response has been enthusiastic and positive. Statistically significant Pearson correlation coefficients have been obtained between student performance on these tests and clinical evaluation and NBME Part II scores. The program has made a valuable contribution to the improvement of evaluation procedures in the Internal Medicine cl
