The National Education Policy (NEP) 2020 marks a significant shift in the Indian education system, aiming to transform it to meet the evolving needs of the 21st century. This study explores the NEP 2020, tracing its roots from previous educational policies, and highlights its provisions, with a specific focus on School Education, including the establishment of Cluster Schools. Additionally, it examines the Standard Setting and Accreditation of schools (SSSA) as a key aspect of the NEP 2020, discussing its implications and provisions. The study begins by analysing the historical context of the NEP 2020, comparing it with previous educational policies to identify the evolution of key principles and ideologies. It identifies the NEP 2020 as a comprehensive and transformative policy framework designed to address the multidimensional challenges faced by the Indian education system. One of the significant provisions of the NEP 2020 in the area of School Education is the establishment of Cluster Schools. These schools aim to promote collaborative learning, resource sharing, and increased efficiency by clustering multiple schools under a common administrative and academic framework. The study explores the concept of Cluster Schools, delves into their benefits, challenges, and potential implementation strategies, and provides relevant state examples that have successfully implemented this model. Furthermore, the study investigates the Standard Setting and Accreditation of schools (SSSA) as a vital component of the NEP 2020. SSSA is envisioned to ensure quality education by setting standards, evaluating schools, and promoting continuous improvement. The research examines the provisions and guidelines related to SSSA, discussing the impact on school infrastructure, curriculum development, teacher training, and assessment practices.
