First of all congratulations to your daughter
I know this won't probably chime with the rest of opinion on here, being an advanced driving forum and all that, but I would pursue a slightly different tack.
Learning to drive is a stressful time, a bit like exams. Once it's over, it's nice to be able to relax for a while, rather than starting out on a new regime of learning straight away. I would say maybe have 3 or 6 months away from driving instructors, just driving (and most of that time WITHOUT a nervous Mum or Dad in the passenger seat), and THEN maybe embark on the new schemes.
If different conditions crop up during that time - e.g. night driving, fast trunk roads etc. then maybe take an experienced passenger along the first time, or the first couple of times, but also it's important for confidence for her to feel that she's not being mollycoddled or monitored ALL the time. Work up gradually to the more difficult tasks, and it'll be less stressful, imho.
It'd be interesting to hear from the lady herself.
