My son was born in July 2007.  He will turn five and I want to send him to kindergarten in fall of 2012.  This will be a sort of "test run" year.   At the end of the year, do I have the right to hold him back?  Or does the school have a say in it?  

I want to be the be all and end all in that decision and I'm afraid the school will overrule me?  Does anyone know the law?
