With the national number of GMAT test-takers rising to 267,000 last year, India is clearly a big source of b-school applicants. We wrote about the GMAC’s new office in the country a couple of months ago, but that’s not the only US-based institution looking to India for expansion. According to this article, several American business schools hope to build campuses on the subcontinent.

Why now? Historically, foreign schools haven’t been allowed to operate in India. Instead, they’ve had to partner with native institutions. But the Indian parliament is currently considering a bill that would open the country’s educational system to outsiders. American institutions including Duke’s Fuqua School of Business are marshalling forces to open new Indian outposts as soon ASAP if the legislation goes through. They’re talking to local officials, shopping for land, and drawing up building schematics.

The bill comes in response to ever-increasing demand for spots at the nation’s top universities and business schools. Application rates are simply too high for existing schools to accommodate, and many students don’t want to go abroad. The numbers are staggering. One figure estimates India will need 600 more universities and 35,000 more colleges over the next 12 years. India has 14 million enrolled students; the Parthenon Group, an educational consulting firm, estimates economic growth will boost that number to 22 million by 2014. “The volume of students looking for education is just unbelievable,” says Eileen Peacock, VP for the Asia office of the Association to Advance Collegiate Studies of Business.

Lots of details aren’t clear yet, like the tuition and fees schools could charge and how the admissions process will work. Plus, universities will have to cough up an $11 million fee to enter the country. And there’s no guarantee they’ll be able to attract Indian students in large enough numbers, especially the less well-known institutions. But they’ve certainly got plenty of demand to work with.
