Item characteristic

Webbecause, by definition, an item characteristic function is a regression func-tion on the examinees’ unidimensional latent trait, θ. In other words, by nature, IRT models deal with item difficulty and variability issues condi-tionally and thereby are more sensitive to individual item characteristics than the classical approach is.
