As a parent myself, I understand how daunting it can be to accept that your (not so little) child is of driving age. I encourage all of my pupils to involve their parents in their driving journey. I am always happy to discuss their progress with parents, answer any questions they may have or just be there to offer reassurance of their progress.
Ged and Claire Wilmot from gedandclaire.com have put together a very good guide for parents. Please have a read of it.
