-Know the Curriculum
The academic curriculum should not be taken for granted and should be checked with a boarding school in India well in advance. As a parent you better know the potential and capabilities of your child, both overestimating and underestimating those are a risk. It is okay to have a specific something in mind before finalizing the school and what works in this condition is consulting with the faculty for those.
-Help your child to overcome homesickness
All these lengthy measures will be of no help if your child will not get to terms with the fact they will no longer see you once back from school. Make them feel secure in the school environment since it is the feeling of security and assurance that they look for when they get back at home.
-Check if the school is credible enough
It might just sound too simple and obvious but most parents miss on this. However it is necessary that parents research extensively about the good will of the school. Check the academic results, talk to the students and their parents to get a fair idea about the plausibility of your decision.
