Comparing the passing rates of nursing students participating in the objective structured clinical examination using fixed score, Angoff, yes/no Angoff, and 3-level Angoff methods ^†

Abstract Objectives To compare the frequency of passing scores of nursing students participating in objective structured clinical examination (OSCE) by 4 methods of fixed score, Angoff, yes/no Angoff, and 3-level Angoff. The OSCE is a valid and reliable tool to evaluate the competency of nursing students. To have a fair judgment in OSCE, it is important to determine the standard setting. Methods In this descriptive-analytical study, which was conducted in 2022, the 7-station OSCE scores and the passing rates of students were compared based on fixed score, Angoff, yes/no Angoff, and the 3-level Angoff by a panel of experts. The research population included nursing teachers (n = 13) and nursing students (n = 65). Due to the small number of participants, the number of samples in each of these 2 groups was equal to the total number of people in the research population. Results Findings revealed that of the 13 nursing teachers who participated in the study, the majority were female and had a master’s degree. Among the 65 students taking part in OSCE, the majority were males. Results showed that the passing rate varied depending on the type of OSCE station and the standard-setting methods used. Differences in some cases were statistically significant ( P < 0.001). Conclusions Findings suggest that the frequency of passing can vary depending on the method used. It is advisable to consider the average score from multiple methods to accurately determine the passing rate and achieve a more accurate acceptance rate.
