Explanation:

ASER is India’s largest NGO-run annual survey conducted by Pratham since 2005 to evaluate the relevance and impact of its programs. Findings are disseminated at national, state, district and village levels, and influence education policies at both state and central levels. The ASER survey reaches almost every rural district in the country and covers more than 15,000 households and 650,000 children each year (the sample size is more than twice that of the survey rounds conducted by the government's National Sample Survey Organization or NSSO). The ASER model has been adapted for use by thirteen other countries across three continents. These countries came together organically to form the People's Action for Learning (PAL) Network
