Multiple Test Equating Using the Rasch Model.
Brigman, S. Leellen; Bashaw, W. L.
Procedures are presented for equating simultaneously several tests which have been calibrated by the Rasch Model. Three multiple test equating designs are described. A Full Matrix Design equates each test to all others. A Chain Design links tests sequentially. A Vector Design equates one test to each of the other tests. For each design, the Rasch model test equating constants were obtained for four reading vocabulary tests. The standard errors of the constants based on each design are also provided and the appropriate use of each design is discussed. (Author/DEP)
