The document analyzes the impact of changes to India's National Institutes of Technology (NIT) admission policies in 2007 and 2008 on cultural and regional diversity among students. It finds that the pre-2007 policy of reserving a fixed number of seats for each state promoted greater diversity, while the post-2007 common entrance exam and caps on home-state enrollment have reduced representation of some regions, particularly the Hindi Belt states in northern India. Statistical testing confirms the changes in student demographics are linked to the policy shifts. The author calls for further study using more institutional data and student characteristics to better inform admission policies.
