The ASER survey is coordinated by ASER Centre and facilitated by the Pratham network. Around 30,000 volunteers from local partner organisations in each district conduct the survey. Many different kinds of institutions partner with ASER: colleges, universities, NGOs, youth groups, women’s organisations, self-help groups and others. See the partners document for more information. A district level training workshop is conducted to train volunteers in how to conduct the survey. Thereafter, each team of two surveyors is assigned a sampled village, where they spend two days (usually Saturday and Sunday) conducting the survey. See the process documents page for detailed information.
