WebIRT Models 3PL Model The famous 3-parameter-logistic (3PL) model was introduced by Birnbaum [1]. The 3PL model uses three item parameters ( a, b, and c) and one ability parameter ( θ) to describe the interaction between an item and a person. The three item parameters are often referred to as the discrimination, difficulty and pseudo-guessing.
