This dissertation aims to analyze the items and dimensions of quality related to apartments in the city of Santa Maria / RS. It is underlined that quality investigated comes to compliance with the characteristics required by customers. About the methodological proceedings, 39 characteristics of location qualities, position and typological were listed according to the bibliography and sequentially reviewed by the real estate agencies. Subsequently, on the real estate agencies, data were collected of 500 apartments sold on 04/01/2013 to 08/25/2014; representing 37% of apartments sold in the city in that period. The data analysis began with the classical theory of tests, using Exploratory Factor Analysis and Confirmatory Factor Analysis sequentially, using the varimax rotation; which identified two factors, based on the criterion of Kaiser. Thus, the approach of Item Response Theory was opportunity, with the logistic model of two parameters as well, the presentation of the critical aspects on the use of Item Response Theory. The first model of Item Response Theory, whose latent trait was named quality of apartments about status, are compost of four items; while the second model, the latent trait quality of apartments about utility, no identified items Sequentially, it was found that the analyzed apartments had scores between 80 to 90, thus, it is clear that most of the apartments investigated for status have the score features 80 in ITR. Therefore it is possible conclude that the proposed objective of this dissertation was achieved.
