Hi

To be qualified for primary School teacher you need to Complete D.Ed degree. I.e Diploma in Education. And this can be done after 10+2. As you are graduated you can do B.ed ( Bachelor of Education ) and be a secondary or primary teacher. But without these degrees in education one does become qualified to be primary or secondary teacher. Nowadays teachers are required to give TET exam along with D.ed/B.ed to be completely eligible. So mere graduation is not enough to be primary teacher

Thank you hope I clear your doubt
