Ensaio: aval. pol. públ. educ. [online]. 2015, vol.23, n.86, pp.129-158. ISSN 0104-4036.  https://doi.org/10.1590/S0104-40362015000100005.

The aim of this study was to use the Item Response Theory (IRT) as a tool to assess the satisfaction of students of the Basic and General Statistics course at the Federal University of Santa Maria (UFSM). Through the application of the Graded Response Model (GRM), a measurement scale for satisfaction was created, where the items of satisfaction and the respondents were positioned in the same unit of measure. The results showed that the GRM of the IRT was suitable for the analysis of data, allowing the identification of problematic items, the construction of a scale for student satisfaction, and the identification of anchor levels. The findings will allow the staff responsible for the teaching of Statistics at the institution to identify how procedures can be improved so that teaching becomes increasingly satisfactory.

Keywords : Item Response Theory; Gradual Response Model; Satisfaction evaluation; Students.
