This study examines the predictive effect of parental attitudes on high school students' academic motivation and personal responsibility levels. In this research predictive correlation model, which is one of the quantitative research methods, was used. 368 students attending the 10th grade in 6 different high schools participated in the study. Parental Attitudes Scale, Academic Motivation Scale and Personal Responsibility Scale were used as data collection tools. Independent samples t-test and MANOVA were performed to determine gender effect on parental attitudes, academic motivation and personal responsibility and Pearson Correlation and Multiple Linear Regression were performed to determine the relationship between parental attitudes, academic motivation and personal responsibility. According to the results, parental attitudes are a significant predictor of personal responsibility and academic motivation of high school students. Democratic parental attitude predicts personal responsibility levels by 31.2% and academic motivation level by 25.7%. In this context, it can be said that the support of parents with democratic attitude provides a positive contribution to students' academic success, social and personal competencies.
