Itemresponse theory is the basis of modern testing theory and drives adaptive standardized tests like the Graduate Record Exam (GRE).
the Gaussian parameterization of our IRT models strongly resembles 11 the Thurstone (Thurstone, 1927) and Bradley-Terry- Luce (Bradley and Terry, 1952;Luce, 1959) models of paired comparison and the 1PL normal-ogive and Rasch (Rasch, 1960) models of student testing.
