Check to see if your child's K - 12 school offers a S.E.S. program.
Supplemental Educational Services are offered in low performing schools throughout the nation mandated by No Child Left Behind. If your child qualifies, you can receive top notch tutoring services for free! Remember your child need not be struggling to enlist a tutor or a coach. The rule of thumb (don't remember where I first heard this) tutoring starts at 80 not at failing.

Choose a first, second, and third provider based on your child's individual needs.
