The first day of school varies from district to district. Some schools begin as early as mid-August, while others begin in early September, after Labor Day. The best way to find out when your school year begins is to contact either the school or the district. You can find your child's school contact information on Education.com's SchoolFinder tool: http://www.education.com/schoolfinder/
Just enter the name of the school or your zip code, and it's easy to find.
