Tailwheel airplanes with some rare exceptions can be landed in two methods and if the student has not been taught both methods said student has not been given the proper training to be given a tail wheel endorsement such as the FAA requires.
As you are in Canada and I am in the UK and not teaching for FAA ratings its possibly a moot point.
I stand by my earlier comments with regard to EASA requirements. We can't really argue apples and oranges.....
