    Course Description:
    PSC290: Fundamentals in Item Response Theory

    Item response theory (IRT) has become increasingly popular in the past few decades in a wide variety of fields. Whether it is being used to create computerized adaptive tests for health related quality of life, allow for seamless equating in K-12 educational testing, or to create more precise measurement instruments in psychological testing, IRT has become an essential feature of the modern measurement landscape. 

    This graduate level seminar will be broken into three sections: (1) Overview of classical test theory (CTT), focusing on the assumptions typically made in CTT and how IRT allows us to relax those assumptions. (2) Basic IRT models (2- & 3-parameter logistic, graded response model, etc.), with the emphasis on understanding the parameters and the basic concepts involved. This part also explores different software packages available for estimating the parameters of these models. (3) Advanced topics to provide an overview of the wide variety of potential uses for IRT. Topics include: Linking, Equating, Differential Item Functioning, Measurement Invariance, and Longitudinal IRT Models.
