The aim of this research was to determine the influence of family educational styles on the academic achievement motivation of students in an educational centre, using a quantitative descriptive-correlational, cross-sectional, non-experimental method. To elucidate, academic achievement motivation refers to what a student is willing to do to achieve excellent academic results and reach his or her proposed goals in school. Likewise, 318 students were selected as a sample and the standardised testing technique was applied by means of two data collection instruments, such as a motivation inventory and the Likert-type PSS scale. The results showed that 28.4% of the parents had a disinterested educational style with regard to their children's academic achievement motivation and 43% of the parents had a more open educational style with a favorable effect on their children’s academic achievement motivation; thus 43.4% revealed a low level of this relationship. In summary, there is a certain degree of both positive and negative family educational styles that affect students' academic achievement motivation.
