The aim: The paper tackles the problem of defining the role of parents (social custodians) in the process of resocialization of adolescents in youth educational centres. It is understood that parents (social custodians) ought to work in collaboration with youth educational centres’ staff to improve the outcomes of correctional counseling and treatment. Method: The findings presented in the article rest on quantitative and qualitative research in three youth educational centres. The author provides in-depth analysis of preventive programs and pedagogical documentation, including parent-staff meeting protocols, enhanced by interviews with the directors supervising facility-based correctional treatment in given youth educational centres. Results: The results obtained indicate there is very little family involvement in the resocialization process of the adolescents in youth educational centres. This lack of involvement ultimately affects the development and success of the on-going therapeutic process. Conclusions: Efficiency of the resocialization process is substantially limited due to a lack of sufficient parental involvement in this process. Thus, engaging families into collaboration with youth educational centres’ staff remains a serious challenge.
