Dear Editor-in-chief, Practical exams are frequently used in the training and evaluation of medical students. One of these exams is Objective structured clinical examination (OSCE). OSCE exam is organized objectively in different stations and the examinees are asked to perform certain clinical tasks in each station (۱). One of the limitations of the OSCE exam is the high cost of its implementation (۲). Increasing the number of OSCE stations is related to reducing the measurement error and increasing the reliability of the test (۳). Therefore, reducing the number of stations can save the number of examiners, patients or SPs (۴). In order to deal with the cost problem in the OSCE test, a method called Sequential OSCE has been proposed, which saves resources while claiming high reliability (۵).
