Homeschooling Support Group
This community is dedicated to parents, educators, and students involved with home schooling. Home schooling - also called home education or home school - is the education of children at home, typically by parents or guardians, rather than in a public or private school. If you have chosen to provide education to your children at home, join the group and get support.

Does your daughter have a friend who goes to her same public school? Is there some way to get her involved in extracurricular activities before she goes back so she can meet some other kids that go there if she doesn't know any already?
Did you go to public school and can tell her how the schedule and the classroom rules may be different?
There's no way to really know ahead of time how it will go, but I think you can make it work if you give her information upfront about what it's like and stay available and interested to help if she needs it.
Best wishes to both of you!
