What is the concept of a play school? A play school is a place where little children in their tender age learn the basic walks of life and spend 1-2 hours each day under the supervision of a couple of teachers who are trained to teach these kids. The supervisor-child ratio should ideally be around 1:10 for a good play school in order to uplift the standard of a particular playschool. Playschool has become an important and significant part of a day to day life of a couple where both of them live a life of a corporate.
