If you have no recommendations
Phone around and speak to a few instructors. Below, I have compiled a few relevant questions that you could ask:-
What is the instructor's pass rate for learners taking the practical test for the first time? See Strictly Driving pass rates.
Can you have a reduced-price initial lesson to see how you get on with the instructor?
Will you get a discount for booking a block of lessons in advance?
Is the tuition vehicle modern and well equipped?
What Continuous Professional Development has he undertaken?
If you seem to be getting all of the right answers then arrange a few lessons and it should soon become clear if the instructor is good. read more.
