If anyone missed signing up for Driver's Edge, your in luck! There is another great driving course for 15-21 year olds, the Tire Rack Street Survival School. It's a a 1-day hands on course to truly prepare a novice driver for the difficulties, surprises, and sudden maneuvers you might need to make out on the road. It is taught by race-car drivers and gives adequate time behind the wheel. (Driver's Edge, a great program, is extremely limited in how much time you actually get to drive.) Additionally you use your own vehicle to do the course, which enables you to know the limit of the vehicle you are most likely to drive.
There is a class happening tomorrow (Saturday, May 21st) at Delaware Park Race Track, but I do not know if it is too late to sign-up. You can check the class schedule to see if there are any other classes that are possible for you or your teen to sign-up for.
These classes are $75, but that's probably some of the best money you could every spend! From what I have heard, it's well worth it and people have a great time attending.
