5. Discussion of the results
The attributes of quality identified as important have different degrees for the different participants. This difference was perceived early in the data analysis. This study confirms the validity of the indicators developed by the Federal University of Rio Grande regarding the perception of quality in higher education. The elements indicated in the factor analyses (exploratory and confirmatory), regarding their clusters, resemble the five dimensions of the SERVQUAL model: assurance, empathy, reliability, tangibles and responsiveness. This suggests that the attributes related to these dimensions are those that are of greater importance to students in higher education. In studies such as those of Russell (2005); Nasser, Khoury, and Abouchedid (2008) and Wang, Taplin, and Brown (2011) on students’ perception of quality, in general, the attributes are analyzed without exploring the formation of the dimensions. Studies such as those of Tontini and Walter (2011), Arambewela and Hall (2009) and Eberle et al. (2010) explore the formation of dimensions, but without necessarily linking them to the already consolidated theory of dimensions of service quality suggested by Parasuraman et al. (1985; 1988); Parasuraman, Berry, & Zeithaml, 1991), and Cronin and Taylor (1992; 1994).
