The IRT models included are the three-parameter logistic model, the two-parameter logistic model, the one-parameter logistic model and the Rasch model.

WebIRT equating is complex, both conceptually and procedurally. The IRT definition of equated scores is based on an abstraction, rather than on statistics that can actually be computed. And IRT is based on strong assumptions that often are not a good approximation of the reality of testing.
