What is the meaning of classical test theory?

Classical test theory (CTT) is an approach to measurement that considers the relationship between the expected score (or “true” score) and observed score on any given assessment. ... First, CTT offers a relatively simple and intuitive analysis of response characteristics for an assessment.

What is classical test theory and item response?

Classical Test Theory and Item Response Theory (CTT & IRT) are the two primary psychometric paradigms. That is, they are mathematical approaches to how tests are analyzed and scored. They differ quite substantially in substance and complexity, even though they both nominally do the same thing.

What is the importance of classical test theory?

Classical Test Theory (CTT) is a theory of measurement that defines the conceptual foundation of reliability and delineates methods to estimate the reliability of psychological measures (Furr & Bacharach, 2014). According to the CTT, reliability stems from observed scores, true scores, and measurement error.

What are the assumptions of classical test theory?

Assumptions of Classical Test Theory

The expected value of measurement error within a person is zero. The expected value of measurement error across persons in the population is zero. True score is uncorrelated with measurement error in the population of persons.
