The sample in this study amounted to 124 students. Determination of the sample in this study using a random sampling technique. The method used in this study is a questionnaire. The analysis used in this study is simple regression and multiple regression. The results showed no effect between authoritarian parenting styles on student learning outcomes at 4.4%. There is an influence between parenting parents in the democratic category on student learning outcomes at 5.4%.
