Currently, access to higher education is imbalanced by high demand and low availability of places in public universities. Therefore, standardized tests are used to a national level to select the new incoming  students, based on a equal opportunities policy. This paper revises the results of successful applicants for the 2005-2006 session at the Autonomous  University of Yucatan Mexico. The test used is known as EXANI-II and was designed by the National Center for Higher Education Assessment (In Spanish: CENEVAL). Results in the EXANI-II were correlated to academic performance up to the fourth semester for each student, in order to find how the selection test is related to the future performance of the selected students. A positive relationship was found between some areas of EXANI-II and general academic performance. For the students undertaking the academic program of Infirmary, no relationship was found between results in the EXANI-II and academic performance up to the fourth semester. For those in the programs of Economy, Veterinary, Biology, Mathematics and Computing a relationship was found between results in the EXANI-II and academic performance up to the fourth semester.
