Why do some driving instructors say that they cannot or will not allow their student to go and do their driving test that they have booked, or more properly that they will not allow them to use the driving instructor's car? This usually happens when the instructor feels that their student is 'not ready for the test yet' but if they felt they were ready then they would have had no issue allowing the student to use their car for the purpose of the test.
It's strange because why would the driving instructor care? It's not like it is their money being wasted if the student fails and it is not like the test centre/driving examiner lose out as they still get paid. It also does not impact anyone else as such a student would have booked a test fairly.
I asked my driving instructor this because she has been suggesting that I reschedule my test and have seen this happen on social media and she vaguely said something like, 'If a student fails their test then the test centre would start asking or wondering why the driving instructor has let them go for the test'. But, again what business is it of the instructor or test centre?
I also read somewhere that it may negatively impact the reputation of the driving instructor's firm if a student failed as it would harm their pass rates, but doesn't that already happen with students who are encouraged to take their test as their instructor feels as though they are ready to do so but then end up failing?
