Be aware that SCCA treats schools, equipment and drivers differently. You enter a school as a novice, without any experience, but your car can't. It must pass the same tech it would pass if it were to enter a sanctioned race event, and the specs can be tough. You can't drive up in a street car and expect it to be allowed as your ride in a drivers school, nor can you show up and expect to enter in jeans and Tshirt sporting your motorcycle helmet. If anything, SCCA is a stickler for safety, and a cosmetic roll hoop and 5 yr old belts won't cut it.
As to their approach, it's different too. A liscensing school won't teach you how to race, nor is it intended to. If you want to learn better driving, go somewhere else. What they will teach you is the RULES of racing, and much/most of their instruction is so tailored. They will attempt to expose you to race conditions involving cars of varying performance thrown together, with situations involving as many flagging situations as possible, and crowded conditions can be great teachers. They will also instruct you in gridding, flying starts, impound, etc. In short, theirs is a true RACING school as opposed to a DRIVING school, and when/if you graduate you do so because they are convinced you know the RULES as opposed to the ART.
Of course you have to go fast enough too.
