D.Ed

Hello,
To answer your question, both the courses aims to prepare teachers for the elementary stage of education, I.e. classes I to VIII. The aim of elementary education is to fulfill the basic learning needs of all children in an inclusive school environment bridging social and gender gaps with the active participation of the community.
Technically, there is no difference except the course name.
Both courses are designed for Elementary Teacher Training I.e. Upper Primary (Class VI to VIII).
Students may join D.Ed or D.El.Ed course after class 12th (Senior Secondary).
Important Points to remember: Both course should be 2 year Duration, the college/institute should approved by NCTE.
If you qualified D.Ed or D.El.Ed after 10th+2 you can apply in TET Exam (Paper I) I.e. for Primary Stage teachers.
If you have 10+2+3 and D.Ed or D.El.Ed degree, you can apply TET Exam (Paper I and Paper II both).
I hope this helps.
