Quality of driving instructor courses

I have just conducted some research to check what the quality of driving instructor courses in my town is. I visited all ten driving schools in town. They are usually small schools, but there are also two large driving centres. The price of driving instructor courses is more or less the same in all these schools. I had prepared a survey the day before. I asked some participants to fill in the questionnaire. They were asked if they liked the teaching methods, if they are offered enough practical training and if they think they are being taught by well-qualified staff. The trainees were also asked to add their own comments concerning the course. I took the questionnaires home and spent two nights reading and analysing them. It turns out that one of the schools offers poor instruction and not enough training. Some of the centres do not provide good equipment or that the trainees are not given free copies of teaching materials. The lectures are also postponed sometimes. The research shows that one particular school offers the best driving instructor courses in town. It"s a small school which does not accept a lot of students, but those who manage to enrol on a course are usually satisfied with the training.
