The article represents the results of the analysis of the development of the positive identity of adolescents, high school students and first-year college students differing in the degree of its intensity at different age. It is revealed that a positive social identity is represented the most brightly at all ages. For the teenage school students the positive behavioral identity is the most characteristic among the components of the interpersonal identity. It is established that the gender positive identity at this age period is poorly presented. Among the first-year college students, despite the same age with the 10-form school students, their positive personal and professional identities are less presented. The results of the research of positive identity have shown that it plays a very important role for adolescents and young men of 13-17 years in their life and life activity. The obtained results are of practical importance for creating conditions for the socialization of adolescents, senior school and college students.
