Vertical Equating Using the Rasch Model.

Journal of Educational Measurement, v17 n3 p179-93 Fall 1980
Three levels of a mathematics computation test were equated using the Rasch model. Sixth, seventh, and eighth graders were administered different levels of the test. Lack of consistency among equatings suggested that the Rasch model did not produce a satisfactory vertical equating of this computation test. (Author/RD)
