A Rationale for Defining Achievement Levels Using IRT-Estimated Domain Scores.
Schulz, E. Matthew; Kolen, Michael J.; Nicewander, W. Alan
Applied Psychological Measurement, v23 n4 p347-62 Dec 1999
Developed a procedure for defining achievement levels on continuous scales using aspects of Guttman scaling (L. Guttman, 1950) and Item Response Theory. Using data from high school mathematics tests for about 6,000 students, found the new procedure to have higher reliability, higher classification consistency, and lower classification error than two Guttman scoring procedures.
