The aim of this thesis is to analyze the relationship between parental expectations and children’s academic achievement. The study was conducted on 157 parents (N = 157) by means of a measuring instrument, which was constructed for the purpose of this research, which encapsulates different areas of parental expectations in regard to education and school, child’s academic achievement, desired level of education for their child etc. The results of this study show that parental expectations relating to child’s university education are closely connected to their academic achievements. This means that higher grades in all subjects, as well as an overall success in school significantly positively reinforced parental expectation of higher-level education of their child. Furthermore, in comparison to previous studies, it is clear that academic achievements decrease with age and that there is a discrepancy between parental expectations and opinions relating to gender of parent. Moreover, study also shows that a high level of academic achievement is believed to be closely connected to parental influence on their child’s success. The results of this research have practical implications in the area of working with parents and educating them about the role of their personal opinions and expectations in regard to their children’s academic achievements.
