I don’t think athletes want to pass fitness tests, at least not the ones worth keeping around.
The athletes worth keeping around, the ones that will help change a program, want to be acknowledged for their work. They want you to complete the circle by acknowledging that they strived for something and that they changed because of it. Passing an arbitrary fitness test is nice, but it’s not the point.
The same goes for classroom tests, and the same goes for salary raises. People want to be valued before they want to be rewarded.
