Am I a parent or a counselor?
This is pretty simple.
If it's student related, you're the parent, and you stay out of it (or offer advice but don't take over).
If it's school related, you're the counselor, and you handle all things school related (e.g., school profile, counselor letter, etc.).
Who should contact the school?
The student should *always* contact the school for any questions related to the application, to show demonstrated interest, for any questions about visits, or for any other comment or question.
The one part where the parent can contact schools is the financial part.
The parent should contact the school if they have questions about the school info. An instance of that would be if you have a question about how the admissions office would like to see school documents submitted, the length of the counselor letter, or anything else that a typical school counselor would ask.
TIP: If you contact the admissions office directly, you'll most likely get the cold shoulder. To keep that from happening, start with this phrase, "I'm the parent of a homeschooling applicant, and I'm calling in my capacity as my child's school counselor."
