Definitely doesn't help to be attending an out of district school (and I know when you were choosing schools that was one of the cons back in the day). But, you will meet people now through volunteering. Is there social media for the school and/or activity? For example, our marching band has a very active Facebook page. Fantastic place to ask questions and learn stuff. You could always start one if there isn't one. "Parents of..." Sometimes if you see a need, you need to fill it. Or just accept that you might not have access to info you want/need.
If the director has emailed you then it is ok to ask some questions but be thoughtful with what you ask. Your list was really, really long. "r
equested a schedule of events, an explanation of the different orchestra groups on campus (which apparently we are part of?), explanation of the COVID protocols, what happens in the event of a cancellation, and what volunteering looks like."
Those are obviously all good to know but couldn't you look up the district's policy on covid protocols on their website? Does it really matter what happens if something is cancelled? I would assume you'd have the notice needed to pick your kiddo up at the right time if something gets cancelled last minute. Everything is still in a state of flux with policies and procedures here. Covid cancellations happen. We get emails, Facebook messages and Remind App notifications. Mostly though the kids know before the parents and just rely the info.
Some teachers and activity directors are just better at the communication piece than others. We've had some frustrating coaches over the years but the kids weren't frustrated and that's what is key.
