Verificou-se que os itens mais difíceis tendem a ser mais discriminativos e informativos para selecionar os candidatos mais hábeis. As provas de Inglês, Biologia, Física, Matemática e Química foram as mais difíceis e apresentaram maior poder de discriminação. Em geral o vestibular não apresentou itens com alta chance de acerto casual. Alguns itens tiveram suas estimativas analisadas em maior detalhe e revelam aspectos de planejamento que podem melhorar a qualidade desse tipo de prova.]]></p></abstract>

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[This study aimed to analyze the multiple-choice questions of the 2009-I entrance examination ("vestibular") of the Federal University of Lavras (UFLA) by using IRT and Bayesian inference in order to identify which properties of the items qualify as better or worse, in order to inform new exams. It was found that the most difficult items tend to be more discriminative and more informative to select the most skilled candidates. Tests of English, Biology, Physics, Mathematics and Chemistry were the most difficult and had the highest discrimination power. Overall, this "vestibular" did not show that guessing would ensure a high probability of success. Some items estimates were analyzed in detail to unveil planning properties which could be used to enhance the quality of this kind of exam.]]></p></abstract>
