The National Curriculum Framework (NCF) serves as a guiding document for educational reform in India, shaping curriculum design, pedagogy, and assessment across all school stages. This research paper evaluates the evolution and implementation of the NCF 2005 and NCF 2023, highlighting their philosophical foundations, pedagogical shifts, and classroom implications. The study explores how NCF 2005 emphasized constructivist learning, holistic development, and child-centered education, while NCF 2023 advances these ideas by promoting competency-based learning, multidisciplinary approaches, experiential pedagogy, and integration of 21st-century skills.

The study concludes that aligning classroom practices with the NCF’s holistic and competency-based vision is essential for achieving inclusive and quality education in India...
