Maintain your teacher/student relationship.
Just because your six-foot son now towers above you doesn't mean he is in charge. Any actions or words of disrespect must be dealt with consistently. In addition, whether your child is learning difficult subjects along with you or you need academic support, be sure to reinforce that you are still the leader in the house.
Provide space for independence.
By high school, your child should have the tools and study habits needed to learn independently, and if your child plans to attend college, he will need to know how to study on his own. You should continue to introduce new concepts, review, grade daily work, and monitor assignments, but depending on your child's self-motivation, you can let him establish his own study schedule as much as possible.
Although teenagers are growing and require more sleep, work responsibilities should be expected from them. Be sure to assign them some good, old-fashioned work to burn off their high-octane energy and instill work ethics that lead to successful employment. Bored teenagers are a threat to themselves and others, so channel their strength into something useful.
Treat them as adults.
Your teenager no longer wants to be treated as a child. Respect his privacy and confidences, but also establish boundaries and guidelines for his conduct and be unified with your spouse when enforcing them. Allow your teenager to suffer the consequences of his decisions, good or bad, and remind him that hormones are no excuse for bad behavior.
