WebItem Response Theory (IRT), which is a more developed and contemporary approach. CTT is relatively easy to understand and has some useful techniques and outputs; by contrast IRT is conceptually more complex but produces a much more comprehensive analysis of an assessment, which takes into account both student and exam item behaviour.
WebIRT takes into account the difficulty of the questions and how the answers that were correct score against others, and even other tests given. There are four sections, and for each section, you need at least a 30% or higher to pass. These are also ranked based on difficulty. WebIRT is the statistical basis for analyzing multiple-choice survey or test data for researchers, social scientists, and others who want to create better scales, tests, and questionnaires. You will explore key foundational concepts of traits, items, and scales and scores, before moving on to learn how to measure and model response data.

A strength of IRT is the ability to visually examine item and scale characteristics using various plots. These plots display how each item and the total scale relate to the latent trait across trait values. This capacity is where IRT methods have an advantage over classical test methods and CFA/SEM methods.
WebIn an IRT model analysis of item response data, the main objective is to estimate each examinee's ability of the test, each item's difficulty level, and perhaps, estimate the regression coefficients of one or more (examinee-level, item-level, and/or judge/rater level) predictor variables.
