Choice of Driving Instructor / School

Hi Everyone, 

I was wondering if anyone could give me any advice on how to choose a driving instructor / school?  How did you decide who to go with, was it to contact people from a 'google' list in your local area (I did this for an older sibling without ASC). My daughter is 17 and very keen to learn to drive, she doesn't have any motor skill issues but does need lots of time and patience to build her confidence.

Thanks in advance.
