Adolescence is an important period in the process of constructing personal identity, particularly at times of educational transi tion. One such transition occurs at the end of compulsory secondary education and it results in an important biographical assess ment of the school career that the adolescent has pursued. One factor that appears to be fundamental in this career is the dynamic of human relations. Focusing our attention on students, we have examined their percep tions of this matter, shaped by their level of personal maturity and linked to their aware ness of their identity status or style. A bio graphicalnarrative approach was used with a sample of 121 students, using quantitative and qualitative techniques and instruments (EOMEISII questionnaire, autobiographical accounts, interviews and discussion groups). We have observed differences in young peo ple's perceptions depending on their level of maturity. At the same time, by comparing their perceptions as a whole, we can see that their family (the main agent in the construc tion of their identity) and peer group, more than school, are the most highly valued areas. Quality educational processes appear to require careful interpersonal relationships, regardless of the areas in which they are de veloped. Corroborating various deficiencies in human relationships through adolescents' perceptions alerts us to their importance. The need to find suitably contextualized models for convergence between the main areas in which our students develop is also shown. This study involves the identification of cer tain elements that play a role in advancing the process of achieving personal identity. These require attention if the development of personal maturity during the compulsory stages of our school system is to be improved.
