If South Asia is going to be part of a world where all children can lead productive lives and be responsible citizens when they grow up, it is important to focus not only on children attending school but also on those who are out of school. Much has been achieved in South Asia in getting more children to school. national legislation and policies are in place in line with international frameworks like the Convention of the rights of the Child (CrC). Governments have shown strong commitment to upholding the right to education for all children. yet, the unfortunate reality is that the numbers of out-of-school children in South Asia are simply staggering. The latest UIS data indicate there are 7.57 million children between the ages 5 to 10 who are not attending school in the South Asia region. Another 25.29 million children between the ages 11 to 13 should be in secondary education but are not in school at all. These numbers make South Asia the region with the second highest number of children not getting an education, after Sub-Saharan Africa. This study is primarily based on the country reports from Bangladesh, India, Pakistan and Sri Lanka. The first three countries are the most populous in South Asia and home to the majority of out-of-school children in the region. The South Asia study and the country studies aim to understand the scale of the problem of exclusion of children in the four countries as well as in the region. This study shows there are a total of 27 million children out of school in Bangladesh, India, Pakistan and Sri Lanka, of whom 17 million are of primary school-age and 9.9 million of lower secondary school-age. Children not attending school are in most cases unaccounted for in school records. They are therefore "invisible" and often not considered in policy and decision-making. The lack of data and information on children who are the most excluded from education are making it even more difficult to reach these children. In addition there is a lack of tools and methodologies needed to identify children who are not attending school. We hope that this study, which is part of the Global Initiative on out-of-School Children, will equip countries with a methodology to better understand who are the children excluded from education, and come up with better solutions. This study highlights individual and household characteristics of out-ofschool children-information that are crucial to make informed policy responses targeted at barriers facing specific groups of children not in school. Profiles of children attending school who are at the greatest risk of dropping out have also been reviewed. If pushed out from the education system, these children are likely to become the out-of-school children of tomorrow. Prevention is better than cure. If policy responses can target at-risk children, and prevent them from dropping out, the scale of exclusion will diminish over time. In order to realize the rights of ALL children to education, political commitment and adequate policy responses are needed to address excl...
