Purpose: This study examines the factors influencing educational aspirations among adolescents in secondary and high schools across Kazakhstan, Kyrgyzstan (officially Kyrgyz Republic), and Tajikistan, with a focus on their aspirations for higher and postgraduate education. Through an analysis of a sample comprising 1360 students from grades 7 to 11, the research explores the likelihood of these students pursuing tertiary education. Design/methodology/approach: The ordered logit regression models were used to analyze the impact of variables related to family background, including parents' education, family support and SES, and school grade. Additionally, the Exploratory Factor Analysis was utilized to distill a smaller set of underlying factors or constructs from the measured variables. Findings: The findings indicate that the mother's education level is significantly more influential compared to the father's education in shaping adolescents' aspirations for higher and postgraduate education in the Central Asian context. Additionally, hypotheses concerning the influence of family socioeconomic status (SES), family support, and grade-level differences on adolescents' higher educational aspirations have only been partially confirmed. Originality/value: To the best of the authors' knowledge, no prior research work has indicated a significant impact of a mother's education on the educational aspirations of her offspring in the Central Asian region. This trend is consistent with the concept of educational hypogamy, wherein mothers possess higher educational levels than fathers, a phenomenon that is gaining prominence in contemporary family dynamics.
