Here's a list of some tutoring-related links.  Hope they'll be of use to you!

Here are a few links to local education-related sites.  (This is not meant to be an endorsement of these organizations, just a list of some sites I thought you might find interesting...)

Virginia Department of Education

Fairfax County Council of PTAs

Fairfax County Public Schools

U.S. Department of Education - Publications for Parents

FCPS list of "Web Sites of Interest to Students, Parents, and Staff"

Commonwealth of Knowledge, Standards of Learning (SOLs)

The Idea Box

Independent School Guide - A directory of private schools in the D.C. area (for sale).

Teaching Strategies Inc. - An interesting site, focused on K-3, with lots of info for parents and educators.

Not in the Washington D.C. area?  Sorry, I can't help with tutoring, but you might try one of these nationwide services.

Tutor 2000 - A nationwide tutor referral service.  It's free to both parents and tutors, and allows them to make their arrangements independently.  Tutors aren't screened, though -- you'll have to do that yourself.

TutorFind - TutorFind has been around for years and is now online.  They do basic screening of their tutors and handle scheduling and payment.  (Although it's a good resource for parents who don't know any tutors in their area, it's usually better to work with a tutor directly if you know one.)

Huntington Learning Center - These centers exist all around the country.  I don't think they're on the web yet but you can call them at 1-800-692-8400.
