It's been many many years, but the SCCA (Sports Car Club of America) puts on one of the best drivers schools around. Especially for the money. It gives you considerable classroom and track time. There are several instructors. Many are driving the course while you are going around. They will lead you around, show you the line and point you to where you should be, and where the breaking points are. The rest of the instructors are stationed around the course at different turns taking notes on all the drivers. Last I knew there was at least one class room day and two weekend track days.

Additionally they have all the support people and equipment at the track. This includes emergency vehicles, ambulance, tow trucks, turn workers, communications, and more. If you have a "mishap" you will be glad those people are there.
