Theoretical and empirical researches of components of structure, content characteristics, types and determinants of family self-determination of modern youth have only recently begun to appear in developmental psychology. Valuable orientations as a factor influencing the process of family selfdetermination of students have not been studied enough. Research objective is to identify features of family self-determination of student's youth depending on the structure of valuable orientations at different stages of age development: youthful age (from 17 to 19 years), early adulthood (from 20 to 22 years). 1086 students of Astrakhan State University, Astrakhan Branch of Russian Academy of National Economy and Public Administration under the President of Russian Federation participated in this research. Depending on the structure of valuable orientations, using divisive clustering of the empirical sample, we divided all respondents into three homogeneous clusters: 1) orientation on the values of professional self-realization (193 respondents, 17.8 %); 2) orientation on gnostic and aesthetic values (274 respondents, 25.2%); 3) orientation on the values of personal life (619 respondents, 57%). The structure of valuable orientations is an important factor determining the process of family self-determination of student's youth. Valuable orientations have an equal impact on the development of cognitive and motivational components of students ' family self-determination. The structure of valuable orientations largely determines the features of the development of value-emotional, reflexive, and regulatory-behavioral components of family selfdetermination in adolescence compared to early adulthood.
