In psychometrics, item response theory (IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables. It is a theory of testing … See more The concept of the item response function was around before 1950. The pioneering work of IRT as a theory occurred during the 1950s and 1960s. Three of the pioneers were the Educational Testing Service See more The IRF gives the probability that a person with a given ability level will answer correctly. Persons with lower ability have less of a chance, while persons with high ability are very likely to answer correctly; for example, students with higher math ability are more … See more As with any use of mathematical models, it is important to assess the fit of the data to the model. If item misfit with any model is diagnosed as due to poor item quality, for example confusing distractors in a multiple-choice test, then the items may be removed from … See more Classical test theory (CTT) and IRT are largely concerned with the same problems but are different bodies of theory and entail different … See more Broadly speaking, IRT models can be divided into two families: unidimensional and multidimensional. Unidimensional models require a single trait (ability) dimension $${\displaystyle {\theta }}$$. Multidimensional IRT models model response data … See more One of the major contributions of item response theory is the extension of the concept of reliability. Traditionally, reliability refers to … See more The person parameter $${\displaystyle {\theta }}$$ represents the magnitude of latent trait of the individual, which is the human capacity or attribute measured by the test.
