The high school level you will have more opportunity for discussion, yet there may be some behavioural problems.

Get all of the certifications you can. That way, if you don’t like one grade level you can be ready to switch, and you’ll be easier to hire since you can do so much. Some states allow you to just take a test and add on to your certification, while some make you take classwork. Check with your state DOE for their requirements.

There is a tremendous difference in high school and 4th grade. Maybe you should observe both classes for a few weeks to see if that gives you a better idea of what you would like. Make sure to visit more than one class in each grade level so you can see different people’s styles.

Good luck!
