Hello Ram!

Yes, you are eligible to apply for teaching posts as a PGT( Post Graduate Teacher) for senior secondary classes after completing your M.Sc and B.Ed. course. KVs provide the best scopes here. But additionally, you will have to qualify CTET - Central Teachers' Eligibility Test ( specially for KVs) or state level TET exam and clear interviews conducted by the individual institutes to get your job whenever vacancies are published.

Hope this answer helps you.
