Concept:
The Integrated Teacher Education Programme (ITEP) is a significant reform under the National Education Policy 2020, aimed at elevating the status of the teaching profession.
Step 1: Evaluating Assertion A.
ITEP is indeed a 4-year dual-major holistic undergraduate degree. It was formally rolled out in pilot mode for the academic session 2023-24. It allows students to save one year by completing the course in four years instead of five (3 years for graduation + 2 years for B.Ed.). Thus, A is correct.
Step 2: Evaluating Reason R.
While many developed countries have high-quality teacher training, it is inaccurate to say "all" have 4-year programs or that this is the sole reason for India's launch. India's shift to ITEP is based on internal pedagogical needs and NEP 2020 recommendations rather than a simple imitation of a universal global standard. Thus, R is not correct as a generalized statement.
