If you want to be a School Teacher, then the qualifications required is that you must have completed education in a relevant subject of studies followed by a BEd (for primary section). For Higher Secondary section one need to have completed the PG course in relevant subject along with a BEd.

Now paramedical course aren't at all relevant to the course of school education in India. So you may not be eligible to get in school education system, but obviously you can teach private tuitions in different platforms.

I hope this helps. Wish you a great day!
