Applying the Rasch Model to test administration.

The Rasch Model is offered as a valuable means to analyze what occurs when students take tests. Unlike Classical Test Theory, the Rasch Model is not sample dependent; it generates data about the test items and the students who took the test. Test item values, item fit statistics, person measures and person fit statistics are some of the results obtained when one uses this model. Through the application of the Rasch Model described here, one may assess its value particularly to nurse educators who address many variables when administering tests. This model facilitates analysis of these variables. Additionally, it allows for comparison of test item values and person measures on the same linear scale. The result of the application of the Rasch Model is a more refined measurement of test item difficulty and student performance.
