This article describes a study on the features concerned with the validity and reliability of the faculty evaluation tool by using corroboratory and exploratory factorial analyses tecniques. The first hypothesis put forward is that the faculty evaluation model of the Universidade do Sul de Santa Catarina consists of eight correlated dimensions: requirement, evaluation, content, method, professor-student rapport, productivity, ethics and professor-course rapport. Corroboratory studies, however, have shown that the model displayed some inadequate statistical indexes. By re-evaluating the structure of the tool through an exploratory factorial analysis technique, a structure with only four correlated factors; competence, rapport and ethics, motivation and evaluation, became evident. This structure, put to the test through corroboratory analysis techniques, showed indexes of global, incremental and parsimony adjustments as being ideal from the statistical standpoint.
