Would you expect them to be au fait with the latest teaching techniques, so that they are able to bring out the best in your child?
Would you hope that the teacher is able to educate, entrall, inspire and motivate your child to learn?
Do you expect the same of your judo coach?
If you are a coach, do you have a moral responsibility to your pupils to keep up your continuing professional development?
I have been lucky enough to work with some inspirational coaches. The main thing I have found that they have in common is that they never stop learning.
Good luck with your coaching.
