An Investigation of the Ordinal True Score Test Theory.

Donoghue, John R.; Cliff, Norman

Applied Psychological Measurement, v15 n4 p335-51 Dec 1991

The validity of the assumptions under which the ordinal true score test theory was derived was examined using (1) simulation based on classical test theory; (2) a long empirical test with data from 321 sixth graders; and (3) an extensive simulation with 480 datasets based on the 3-parameter model.
