The Four-Year Integrated Bachelor of Education (B.Ed.) Programme, recommended under the National Education Policy (NEP) 2020, aims to transform teacher education in India by integrating disciplinary knowledge and pedagogical training from the undergraduate level. This study critically examines the effectiveness of the Four-Year Integrated B.Ed. Programme (FYI-B.Ed.) in selected teacher education institutions in India. Using a descriptive survey method, data were collected from 240 participants comprising pre-service teachers and teacher educators from government and private institutions. A structured questionnaire measuring academic preparedness, pedagogical competence, professional commitment, school internship effectiveness, and institutional support was administered. Statistical tools including mean, standard deviation, t-test, ANOVA, and correlation analysis were employed. The findings indicate that the programme significantly enhances pedagogical competence and subject integration but faces challenges in infrastructure, faculty preparedness, and internship implementation. The study concludes that while the programme has strong structural potential, its effectiveness depends on institutional capacity and policy execution. Recommendations are made for curriculum restructuring, faculty development, and improved school partnerships.
