TAVARES, Cristina Zukowsky. Teoria da resposta ao item: uma análise crítica dos pressupostos epistemológicos. Est. Aval. Educ. [online]. 2013, vol.24, n.54, pp.56-76. ISSN 0103-6831.

This article seeks to reveal concepts and values involved in the act of evaluating and its interface with the idea of measurement. It also addresses some studies on the Item Response Theory (IRT) in the literature in order to assess its potential and limits. IRT was investigated from the perspective of three important epistemological assumptions of the model: unidimensionality, local independence, and quality and appropriateness of items. “How can unidimensionality be maintained if all human behavior is highly complex and multidimensional?”; “How can one prepare test items which are totally independent?”; “Is it possible to create and maintain a database with calibrated and adequate items?”. These are important challenges for the theory and the reliability of the methodology, which are not always infallible.

Keywords : Item Response Theory; Rating Scale; Epistemology; Educacional Evaluation.
