The study universe was constituted by the total of ordinary final exams of the subject Research Methodology and Statistics, on purposive sampling 276 exams were selected. There were used as theoretical method: analysis-synthesis and induction-deduction, and empiric ones: documental analysis, the survey in interview form was applied to six key informants. The correspondence between the duration of the exam and the quantity of items explored in the exam was analyzed, it was calculated the index of difficulty and the coefficient of correlation of the difficulty level of the items exam.
Results: it was evidenced the non correspondence between the time dedicated to each topic and the quantity of explored items, the quantity of easy items overcame the expected percent lightly. There were discriminated in an excellent way most of the items.
Conclusions: the valuation of the applied indicators demonstrated prevalence of the items of average difficulty and excellent discriminatory power. The items that were not discriminated in an appropriate way coincided with those classified as easy, with difficulties in their elaboration and reproductive level of assimilation.
