I don't think that most schools give a toss to be honest.
I have yet to find a school that has a training or development plan for instructors. They do not review flight instructor performance or monitor standardisation in any way whatsoever.
Oh but they are great at taking large amounts of cash off joe public and passing along peanuts to the instructor.
Aviation is a bit of a joke until you secure a job with a "decent" airline (unfortunately they are a dyeing breed).
