Teacher effectiveness is a cornerstone of educational quality and student achievement. In India, recent reforms under the National Education Policy (NEP) 2020, the National Curriculum Framework for Foundational Stage (NCF-FS) 2022, the National Curriculum Framework for School Education (NCF-SE) 2023, and the Samagra Shiksha Abhiyan aim to elevate the quality of teaching across the country. This research paper delves into the concept of teacher effectiveness within the framework of these reforms, exploring how they intend to address challenges in teacher preparation, professional development, and resource allocation. Through a comprehensive analysis, this paper identifies the implications for educational practice and policy, while also highlighting the potential barriers to successful implementation.
