In the realm of learning, teaching and learning occur simultaneously, with continuous learning happening through the act of teaching. This study, attributed to Phil Collins, underscores the symbiotic nature of teaching and learning. B.Ed. colleges exemplify this concept, where student teachers engage in both learning and teaching within authentic classroom settings. This paper delves into the objectives, the role of the student teacher, the efficacy of the teaching program, and the challenges encountered in the B.Ed. Internship Program. According to NCTE regulations, student teachers are required to complete a sixteen-week internship during the second year of the B.Ed. course, fostering comprehensive development. The aim is to assess the internship's impact on trainees' growth and thoroughly examine the challenges they face. The assessment encompasses fifty questions across ten dimensions: classroom management, lesson planning, personal constraints, instructional objectives, infrastructure, workload, emotional aspects, mentoring, educational technology, and evaluation methods. Two hundred samples were gathered from B.Ed. students enrolled in various colleges across Tamil Nadu in India. A random sampling technique was used. Percentage analysis was employed as the analysis technique. The results show that the students highly applied their skills in their teaching practice.
