Yes, hunter safety courses should be allowed in school as many students may wish to become hunters or at least go hunting every now and again. Having a safety course for hunting would be a great boon to these students, and it would teach them how to hunt properly and safely.
A Hunter's Safety course would be a great addition in a school setting. What many public schools miss, while teaching, is real world applications. Because Hunter's Safety courses can teach people how to hunt more safely, they would be a good addition. Even if a student was not interested in hunting they could learn the process and be safer, just by being aware of hunting.
