Abstract: Life-skills can be best understood as the abilities for positive and adaptive behaviour, which enable individuals to deal effectively with day to day needs and challenges. Major life skills include problem solving, decision making, creative and critical thinking, effective communication, interpersonal skills, empathy, and self-awareness, coping with stress and emotions. These Life-skills have further been clustered as; Thinking skills, Social skills, and Emotional skills. Adolescence is the period in human growth and development that occurs after childhood and before adulthood, from ages 10 to19. It represents one of the critical transitions in the life span and is marked by a tremendous pace of physical and psychological human development. Recognizing the importance of life-skills, in the lives of Adolescents the present research was undertaken with the following objectives: To assess the life-skills of the selected adolescents and to determine the variation in their life-skills with their SES and education of parents. School going boys and girls (14-16 years) of classes VII, IX & X were randomly selected from randomly selected schools of five Zones of Delhi Municipal council. SES scale by Tiwari et.al (2010) and Life-Skills Assessment Scale by Subasree and Nair (2010) were used for collection of data. On statistical analysis it was found that Sample adolescents had average level of life skills. Dimension wise analysis revealed that they scored least in the dimension of coping with stress, pointing to the need for more emphasis on acquisition of this skill to deal with the ever demanding requirements of everyday life. A highly significant correlation found between parental education and levels of life-skills of adolescents, further fortify the notion that education plays a crucial role in making parents aware of the needs of their children.
