The Academic Edge is one of several tutoring/academic help centers that seem to be popping up everywhere. We were referred to it through our sons teacher and have been extremely pleased.
They offer tutoring from reading, comprehension, spelling to mathematics of all levels. They also offer writing classes to learn how to conquer essay questions and preparation courses for state tests such as the WASL. They are staffed by teaching professionals who really seem to enjoy the different challenges each child has.
They offer 1 hour sessions each week. I have found them to be extremely accommodating for changes that need to be made for soccer practices and such. They are also open on Saturday.
