The admission of students into Geology, Mines, Petroleum, and Environmental engineering programs in the previous decade was carried out under the responsibility of each Faculty at the Universidad Central del Ecuador; a decade later and by the legal mandate it is carried out by external organizations outside the academy; in the case of this country, the responsibility lies down on the Secretary of Higher Education with the National Leveling and Admission System project, which is supported by the National Institute for Educational Evaluation. Knowledge tests were applied for two times; in the first case, the tests were based on mathematics, physics, and chemistry subjects, while in the second one the same tests were used as diagnostic ones. The results show a considerable drop in the reports and the possible causes of this problem are described and summarized in the change of the type of baccalaureate program offered by high schools run by the Ministry of Education; the little experience of the organizations that carry out the admission process due to their incipient association with the academy, the standardization of the admission test for all applicants to any program in public universities, and the changes in the training of high school graduates cause a kind of education with deficiencies that previously did not exist.
