"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.
