India’s Educational Leadership as Vishwa Guru: The Evolution of Educational Accountability and Teacher Performance From Ancient Times to NEP 2020

India has long been recognized as a Vishwa Guru (global teacher) due to its rich educational heritage, dating back to ancient institutions like Nalanda and Takshashila. This study explores the evolution of educational accountability and teacher performance in India, tracing its roots from the Gurukul system to the contemporary National Education Policy (NEP) 2020. The research highlights how ancient Indian education systems enforced accountability mechanisms through teacher-student relationships, community involvement, and merit-based knowledge dissemination. The study further examines key accountability theories—such as institutional, professional, and performance-based accountability—that have shaped India's education system over centuries. By analyzing historical precedents and modern reforms, the paper underscores India's potential to reclaim its position as a global leader in education through NEP 2020, which emphasizes holistic development, teacher autonomy, and outcome-based learning. The findings suggest that integrating ancient accountability mechanisms with modern pedagogical approaches can enhance educational quality and teacher effectiveness in India.
