The Phases of Expansion

• The Founding Era (1961–1996): Established the "Old IIM" legacy. Starting with Ahmedabad and Calcutta, this era saw the addition of IIM Bangalore (1973), IIM Lucknow (1984), and IIMs Indore and Kozhikode (1996). These institutes set the gold standard for management education, research, and corporate leadership in India.

• The Expansion Era (2007–2011): This period marked a structural shift to scale management education, introducing the second generation of IIMs like Shillong, Rohtak, Ranchi, Raipur, Trichy, Kashipur, and Udaipur to address the rising demand for professional business leaders.

• The New Generation (2015–2026): Focused on regional inclusivity and broader access, this phase added IIMs in Amritsar, Bodh Gaya, Nagpur, Sambalpur, Sirmaur, Visakhapatnam, Jammu, and most recently, IIM Guwahati (2026). Additionally, the transformation of legacy institutes like NITIE into IIM Mumbai (2023) added further prestige to the ecosystem.
  
  

Shaping the Future

Over 65 years, the IIMs have transitioned from "diploma-granting" bodies to degree-granting autonomous institutions. They now serve as the bedrock of Indian entrepreneurship, corporate strategy, and public policy. With the inauguration of IIM Guwahati in 2026, the network has reached a new milestone, ensuring that high-quality management education is accessible across the diverse geography of India.
