My high school has already added my SD to my 504 plan and said that they would send out a letter about service dog etiquette before the beginning of the school year, but they haven't. I'm nervous about how my young SD will behave, and now about the students as well. Should I offer to introduce him to my classmates on the first day of each class? I'm terrified, as I know that high schoolers can be jerks, especially in the hallways, and I can't address all 2500+ students at once.
That’s a really understandable reason to be scared! I think the first step would definitely be to reach out to the administration about the letter they were supposed to send out. That will make the other students that are not in your class a little easier to deal with. But I think that addressing each of your classes at the beginning of each class is a good idea. It would help you set clear boundaries right away!
