What do roller skating coaches and apprentices do?

The coach apprentice is the coach's assistant.

As the name implies: help the coach teach the children and help the coach share the work.

The specific work is unknown, as the case may be!

In addition, the coach apprentice must be promoted as a roller skating coach, which means that when you have the ability to teach your children by yourself, you can hold this position!

Another is that the job advertisement is not clearly written, which may be for coaches and apprentices (roller skaters who need training)

I hope it helps you!
