National Achievement Survey

National Achievement Survey (NAS) is a large-scale study of student learning which is done by the Ministry of Education. It systematically reflects the effectiveness of schooling. The results help compare performance across populations to find the desired direction for improvement.


The Government of India is prepared to conduct a National Achievement Survey for the classes 3, 5, 8 and 10 every three years. On 13th November in the year 2017, the previous National Achievement Survey was conducted with the primary aim to assess the competencies developed by the children who were then studying in grades 3, 5, and 8. The NAS for this year was held throughout India on 12th November, 2021.

Objective of NAS

NAS helped assess learning confusion and new insights during the Covid 19 pandemic. Once evaluated, it helps to initiate corrective action.
