The National Exam for Entrance into Senior High Education (Examen Nacional de Ingreso a la Educacin Media Superior-EXANI-1) has been applied since 1996. It is an exam designed, developed and scored by the National Assessment Center for Higher Education (Centro Nacional de Evaluacin para la Educacin Superior-CENEVAL), as a selection instrument for the entrance process into public institutions of senior high education located in the Mexico City metropolitan area. The objective of this research was to study the degree to which performance has varied, in the five generations that have taken this exam, as well as to study the influence of a number of socioeconomic and educational variables on that performance. The study looked at data corresponding to the total population assessed, the number of which ranges from between 229,000 and 260,000 individuals, using basically descriptive statistics and correlation analysis tools. Among the results obtained, it was observed that parents' schooling, level of family income, type of junior high school attended and average grades received in junior high school are the variables with the most significant relationship to levels of performance on the exam. As well, it was found that intrinsic factors in the schools (such as characteristics of teachers, educational processes and assessment systems) as well as some psycho-affective characteristics of the students (such as motivation for studying, self- esteem) are aspects that have a decisive effect on students' performance on the exam.
