While there are some schools in many states that will hire an elementary teacher to be a HS coach, that is NOT THE NORM. The school schedules are so different between whe elementary and HS start and finish due to things like busing that it is rare to find an elementary teacher do this. My daughter was an elementary 5th grade teacher. She volunteered for both middle school and high school softball teams. It was very hard for her to get to most practices unless the HC decided to wait an hour. Mostly she got there in time to throw some live BP as practice wrapped up. This year, she is going to be paid and so the district told her she had to move to the middle school. She has made the move. If any of you want, take a look at the differences in starting times in your local school districts. Oh, at the school I retired from we have an AC for both the baseball and softball programs. They get to practices 40 minutes after practice starts and get to games right before game time. They get to leave early for away games from their MS duties.
