Course Content

• Item Response Theory (IRT) Models: This foundational unit covers the different IRT models (e.g., 1PL, 2PL, 3PL, graded response models) and their underlying assumptions.
• Parameter Estimation in IRT: This unit focuses on the methods used to estimate the item and person parameters within IRT models, including maximum likelihood estimation (MLE) and marginal maximum likelihood estimation (MMLE).
• IRT Model Fit and Diagnostics: Assessing the goodness-of-fit of IRT models to the observed data, including various statistical indices and graphical techniques.
• Item Analysis using IRT: This unit covers techniques for analyzing individual items within the context of IRT, including item characteristic curves (ICCs), item information functions (IIFs), and test information functions (TIFs).
• Differential Item Functioning (DIF) Analysis: Detecting items that function differently for different subgroups of respondents, a critical aspect of fair and unbiased assessment. This utilizes IRT principles.
• Applications of IRT in Survey Design: The practical application of IRT principles in the design and development of surveys, including adaptive testing and test equating.
• Software for IRT Analysis: A practical unit covering popular software packages used for IRT analysis (e.g., R, Mplus, BILOG-MG).
• IRT and Computerized Adaptive Testing (CAT): Exploring the synergy between IRT and CAT, and the advantages of this approach in survey methodology.
