Introduction of Pre-school in Public schools

I have  been thinking  of this for quite  sometime.The  government  should  introduce  pre- school in public schools.Do you  know  why I have  to say this ? because  for  instance in Kakamega Hill school a child  begins  fro Pre- school hence getting a better  foundation  but  don't  look at it  as a waste of years.
