Welcome to EC. What is it that you would want them to do differently? How would you need them to acknowledge you? If it is simply so that they would know or to just use different pronouns it is probably enough to just talk to them privately. If you are looking for more serious accommodations then it is probably best to have your parents speak to the administration.
Austin.....Just talking to most teachers will be enough. Occasionally you may happen on someone who won't do what you ask, then as @QuietPeace mentioned, you would need to have your parents talk to them. If your parents won't do that or if you're not out to your parents then you may have to just endure. .....David
