If more than 75% of prospective teachers demonstrate they are capable, and there is a need for them, I do not see a reason to turn them away. Any standards should be set according to criteria that are considered necessary for effective teaching, and not relative to what other prospective teachers happen to get on a test.
While the AITA is a valuable project, this bill will also clarify that regions retain their traditional role in being able to set their own standards for licensure according to their needs.
75% might be an arbitrary cutoff, but so is any other cutoff for a standardized test that we might devise.
And, if the perceived problem is a lack of teachers, lowering the barriers to entry isn't going to improve the quality of education.
