Adolescents represent a significant proportion of the population of India. The Census 2011 reports that they constitute about 22% of the population with state wise variations. Adolescents in India are not a homogenous group since they are embedded in their socio-cultural and economic diversities. These diversities at multiple levels starting from the individual to the familial to the social, cultural and governance systems are nested in each other, producing their unique risk and protective factors matrix. Adolescence as a stage, is technically, unique and special. Latest neurological research suggests that, the adolescent brain goes through a growth and differentiation spurt akin to the early childhood. Risk taking behaviours, a unique feature of adolescence are similar to the exploratory behaviours of very young toddlers. All these factors make policy, planning and implementation, which are friendly for adolescents a real challenge; nevertheless, a challenge worth tackling, for the rewards of such an initiative are multifold. With this in mind SIAAP along with UNICEF attempted to assess the current inter departmental linkages within health & HIV, nutrition and sanitation schemes / programmes and with other in school, child protection and out of school programmes for adolescent friendly services at state and district level, the adolescent and community participation and awareness in Salem district vis-a- vis key adolescent programmes in Health & HIV, Nutrition and Sanitation and finally to provide policy recommendations at state level and operational recommendations at district level on how to improve coverage and quality of services and inter-sectoral linkages.
