Admin vs Teacher account

I purchased a homeschool co-op plan. I want to add parents to the plan, so they can add their own children, as users.
I want to make sure that each parent has access to edit only their own kids’ accounts. How do I accomplish it? Do I need to add parents as teachers or admins?

I don’t know I think you can just add them as admins.
My mom set up are accounts and she is just an admin, but she can still add new courses and delete old ones and add tasks to are account.
I could be wrong though if that’s not the help you need than sorry.
