As a benchmark of reform and innovation in Indian higher education, the development of the Computer Science discipline in the Indian Institute of Technology (IIT) from its inception to its ranking among the world-renowned disciplines is of significant research value. Based on the historical research method, case study method, and literature research method, this paper systematically examines the development trajectory of the discipline from 1963 to 2025. It divides the period into three phases: founding and early development (1963-1982), rapid rise (1983-1991), and steady enhancement (1992 to present). The analysis examines the academic platform, faculty, scientific research, and human resources in each phase. It analyzes the initiatives and effectiveness of each phase in terms of core elements, including academic platform, faculty, scientific research, and talent cultivation. It is found that the discipline has realized leapfrog development by following national strategies, integrating international resources, and promoting the integration of industry, academia, and research, etc. Its successful experience and problems hold great reference significance for the development of the computer science discipline in China’s construction of the “double first-class”.
