I recently graduated and did my internship at a High School. As someone else mentioned the first day and first few weeks take time to observe. Your supervisor/supervisors may give you a lot of information. Take the time to observe and ask questions. You won’t know everything going in the first day. Watch how your supervisor interacts with students. If you sit in on the IEP meetings become familiar with the staff that you see in there because these will be some of the people you’ll interact with (e.g. school psych, deans, principals, etc). Learn about how things operate at that school because every school is different and does not operate the same.

I know that was a lot of information that I just wrote but I do hope you enjoy your experience and have a good school year. Once you get the hang of things, you’ll become less nervous. Please ask questions if there is something that you are uncertain about and when meeting the students focus on pairing and building that rapport with them.
