Unless things have changed over the last 10 years, hunter education curriculum for HE classes is standardized between most if not all states. The various state's hunter ed coordinators meet annually to discuss and initiate changes if needed. If there is a need for a change, the change extends to all the states. Instructors just don't make up their own subjects to add to the course. The hunter education course used to be called the hunter safety course when it initially began and was changed to hunter education when more things were added to the program. Hunter education curses are a basic introduction to hunting, safe gun handling, laws ethics etc. You cannot teach first time hunters a lifetime of experience in the length of time the course is given. Parents and other mentors must continue the hunter education once the new hunted is able to obtain a license and go hunting. Hunter education courses are designed to provide basic knowledge to form a foundation to build on, not create a finished hunter. Actually, a good hunter never stops learning.
Gun cleaning, care of game after the kill and preparation for the table, tracking learning where to look for game etc., are things that are learned as we go along. Many sportsmen's clubs and the PA Game Commission in my state do put on classes on how to care for game after the kill but it is not part of the hunter education formal program.
