Introduction

There are different methods to determine the acceptance standard. To establish educational justice, the standard of each test should be determined for the same test so that judgments could be made with the least error and cost. This study endeavors to determine and compare the acceptance standard of nursing students participating in the Objective Structured Clinical Exam (OSCE) using four fixed score methods, Angoff, yes/no Angoff and three-level Angoff.

Methods

In this cross-sectional descriptive study that was conducted in the 2021 academic year, the scores of OSCE of nursing students were calculated and compared by a panel of 13 individuals in seven stations using four methods of fixed score, Angoff, yes/no Angoff and three-level Angoff. The population was nursing faculty and 8th semester nursing students, and due to the small number of participants, the number of samples in both groups was equal to the total samples (13 lecturers and 65 students).

Results

The statistical analysis revealed that the average score obtained in all the stations is 15.79±0.98 out of 20, and the highest and lowest average scores of students are respectively related to personal protection stations(19/27±0.61) and gavage(13.76±2.02).On the other hand, the standard of the whole test and the frequency of the passing rate based on the fixed score methods, Angoff, yes/no Angoff and three-level Angoff are respectively 12(with a pass rate of 95.92%),10.80(with a pass rate of 96.04%),12.48(with a pass rate of 69.67%) and 10.50(with a pass rate of 98.90%) were obtained.

Conclusion

The highest and lowest acceptance percentages were related to the three-level Angoff, and yes/no Angoff. The standard obtained from Angoff was three levels easier. Therefore, it could be concluded that different methods provide different standards. Accordingly, it is recommended to use the average score obtained from three methods (Angoff, Angoff yes/no, three-level Angoff) to reach a single standard.
