Abstract:
This study aimed at estimating the psychometric characteristics of a criterion- referenced test in measurement and educational evaluation according to the Modern Theory of Measurement. For achieving the objective of the study, an achievement test in measurement and educational evaluation was constructed. The test in its final form consisted of (50) multiple choice items. The test was administered on a sample of (222) male and female students. The results revealed that students’ responses for (37) items of the test fit Rasch Model assumptions, whereas (13) items didn’t fit the Model. All items in the final form of the test were located in the range of infit/ outfit statistic. The coefficients of reliability obtained for persons and items were (0.90) and (0.95) respectively. The test validity was ensured through several approaches. The results also showed that information function for the test was maximum at (θ = b) and it was consistent with Rasch Model assumptions. The test presents the greatest amount of information at medium ability level and presents the least amount of information at both the highest and lowest ability levels.
