Abstract

At the beginning of each school year in the subsystem of Higher Secondary Education (HSE) of the College of Scientific and Technological Studies of the State of Durango (CECyTED) and in all the States of the country, the evaluation tool of admission to the school is applied in the test-retest modality in an equivalent way, mediating between both applications an induction course. The purpose of this process is to update and standardize the knowledge of the applicants in the areas of mathematical ability (MA) and reading ability (RA). Given its importance, the study was conducted with the objective of measuring the degree of reliability of the Instrument, parting from the fact that previous bibliographic review shows no evidence of it being the subject of any standardization process. The type of study is instrumental, two psychometric tests were carried out; In a first approach, the quality of each of the questions was determined according to their difficulty and discrimination indexes, as a reference to the subsequent determination of the KR-20 coefficient. The sample in the study was of 34 participants who complied with the diagnostic evaluation process. With the values obtained from the KR-20 coefficient of MA and RA in test and retest, it was concluded that the instrument is reliable but does not achieve the levels of a standardized test.
