This book represents the effort of students of the Master of Education in the field of educational research. This allowed them to demonstrate the skills developed throughout their program, which culminates in their thesis. The research undertaken by them was developed under the theme of the factors that affect the academic performance of students at various educational levels. Each student carried out the research under the conditions in which they were, so the richness that is presented is greater, given the diversity of environments that are presented. With this we hope to contribute to studies on educational performance.
