Item Characteristic Curve Solutions to Three Intractable Testing Problems
Marco, Gary L.
Journal of Educational Measurement, 14, 2, 139-60, Sum 77
This paper summarizes three studies that illustrate how application of the three-parameter logistic test model helped solve three relatively intractable testing problems. The three problems are: designing a multi-purpose test, evaluating an multi-level test, and equating a test on the basis of pretest statistics. (Author/JKS)
