A tour and possibly a day to visit and shadow may help him make a decision.
A few thoughts before you tour the school:
- Print or screen-print a copy of their application form, and talk through the application form with your son.
- Have your son make a resume including special interests, activities, community college courses which counted toward homeschool, any awards, etc. He could include a list of books read if these help to portray him as a high-school student, especially with an interest in global issues, cultural exchange, etc. The exercise of prioritizing and organizing information about himself into a resume will help him present himself well, rather than having a "deer in the headlights" reaction if school staff ask him impromptu questions.
- Help your son make a list of questions to ask of school staff/administrators.
- Have him carry a clipboard or folder during the tour so he can make notes of answers he receives to his questions, and jot down other things which he notices.
- Have him consider sending a "thank-you" letter after the tour, possibly mentioning a tour highlight and something learned/appreciated about the school. If he has this in mind while he preps for the tour, then during the tour he will observe and recall items to incorporate into the letter, after the tour.
