A comparative study of adulthood was conducted to explore the levels of self-esteem and the parameters of adulthood among students at the Aegean University, Department of Food Science and Nutrition (D.F.S.N.) and the students of public Institute of Vocational Training (Greek: IEK), both located on the Greek island of Lemnos. Thus, maturity, responsibility, autonomy, self-management and the sense of social responsibility were measured on a Likert scale and Rosenberg’s self-esteem scale. The research investigated whether being a student of Tertiary Education or a student of Vocational Training has an effect on the concept of adulthood or influences the level of individual self-esteem. The quantitative results brought to light that adulthood can be attained without direct relevance to the Educational Institute whereas the degree of self-esteem and self-management in women was determined to some extent by the choice of School. This conclusion has raised issues of major importance for further research. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0735/a.php" alt="Hit counter" /></p>
