What is the concept of a play school? A play school is a place where around 10-20 children spend 1-2 hours each day under the supervision of a couple of teachers. "The supervisor-child ratio should ideally be around 1:10" says  an experienced   Child Psychologist. She believes that play schools have a lot to offer, and that the play schools should not be aimed at developing  academic skills . She also says there should be no set goals or any stress on performance; the focus should be on the sensory-motor development and the  social development of  the child. She is very much an advocate of play schools since they develop age-appropriate  behaviour at the right time.
