The GST is a mobile learning cart with wheels and flexible boards that can be taken to different places where street children and adolescents are gathered like bus parks, cinema halls, vegetable markets and other such sites so that they can access a learning through different learning materials like games, charts which promote literacy, numeracy and life skills. The GST will operate for 6 days weekly running for half hours time or more at selected sites. The aim of GST is to provide outreach services and minimize the high risks associated with these vulnerable and marginalized groups of children and adolescents. The other objective is to promote these children to the KSK or formal schools.
