Hoffman Academy offers online piano training. I can tell you from experience that Hoffman Academy offers you more content then I have seen on other piano training sites. I was interested in Hoffman for my daughter. We have a piano, she has take a few lessons through a piano summer camp. I played the piano when I was young and can get her started on my own. The Hoffman materials allow her to work at her own pace even when I am not able to dedicate the time she would desire to her training. 

Anyone can watch the video training at Hoffman Academy for free. The supplemental materials require a fee and can be downloaded and printed at home.
