This study intends to determine the effects of parenting styles, as perceived by parents, on high school students' achievement goal orientations. The study was conducted on 497 students and their parents selected via simple cluster sampling from public high schools of the Ministry of Education in Amasya, a city in Turkey. Data were collected by means of a personal information form prepared by the researcher, the Parents Attitude Scale (PAS) and the 2x2 Achievement Goal Orientation Scale. Data analysis includes multiple regression analysis, as well as descriptive statistics. Based on research findings, parenting styles perceived by parents can be listed as democratic, overprotective, permissive and authoritarian. Students' achievement goal orientation follows the order of learning-approach, learning-avoidance, performance-approach and performance-avoidance. Another finding obtained in the study shows a positive and medium level relationship between parenting style and learning approach orientation and a positive and low level relationship between parenting style and learning avoidance orientation. Democratic and overprotective parenting styles were found to have the strongest and the most significant impact on learning approach orientation whereas overprotective and permissive parenting styles had the most significant impact on learning avoidance orientation. Parenting style was found to have a low level positive relationship with performance approach and performance avoidance orientation. Analyses show that authoritarian and overprotective parenting styles had the most significant impact on both orientations.
