Both B.Ed and D.Ed courses will equip individuals with teaching skills. Although these are teaching courses, the training programs are entirely different. B.Ed is bachelors' degree in Education whereas D.Ed is diploma in Education. B.Ed is an undergraduate academic training program that carves up the graduates as teachers in schools. However, D.Ed is a diploma course that qualifies intermediates as nursery teachers in kindergartens. After the completion of +2 you can opt for D Ed. Graduates can opt for B Ed at a B Ed training college or a University department. Higher qualifications include M Ed. MA in Education is also available with some Universities and institutes such as Azim Premji University, IGNOU and Tata Institute of Social Sciences.
