I think the owner of the school will have to first decide, if he requires Government aid or not. In case the Government aid is required, then he should contact the authority who approves and distribute the Government aid. He will be the best authority to advise on the subject matter as ultimately, the Government aid will become the crucial factor. In case the authority requires re-approval of the school for continuing aid after switching over from the Tamil medium to English medium, then the procedure should be completed accordingly. Both Tamil and English medium school exist in the state of Tamil Nadu. Recognition of a private school under the Tamil Nadu Recognized Private Schools (Regulation) Act, 1973 is required for receiving Government aid, which is implemented by the Department of School Education, Government of Tamil Nadu.
