Hello! I was homeschooled throughout high school and am now at the Academy. Is your daughter a class of 2019 or 2020 applicant? I couldn't be sure from your post.
I would advise your daughter to be prepared to talk about homeschooling during interviews. As far as I'm concerned, homeschooling has been a strength, not a liability--be proud of it! Some starting points could be talking about time management, being able to fit in with groups that she doesn't have a lot in common with, and willingness to buck peer pressure.
While GPA will still be listed on your portal, I've heard that it's essentially thrown out for homeschooled candidates. The community college GPA might hold some weight. Your own classes? Probably none. Good test scores are imperative, as they will become the bulk of the Academic part of the WCS. I had 700+ in all three sections of the SAT. I also took a couple of AP tests--Physics B after self-study, Calc AB and BC after online courses, and English after a course. Physics is very self-preppable--I had a textbook and a study guide, and I got a 5. You could feasibly self-prep a number of APs. All of those just help to validate GPA. Also--how do you accredit? I used a private school. Not sure if that helped, but it didn't hurt.
One thing you will NOT find anywhere is that homeschoolers (as of last year, at least) are required to submit a "homeschool profile". Basically, a philosophy statement & homeschooling overview. Mine was about 5 pages long; I took it as an opportunity to convince the admissions board that I was a really, really good academic candidate. You know best what your academic strengths are, and how you've been verifying performance. There are no specific guidelines, so it's a great way to talk in depth about your schooling methods. I included tests I'd taken, math team participation, online school (outside grades), college courses, and private school accreditation as "proofs" of competency.
Athletics & leadership are also really important. Your daughter swims--that's great. A varsity letter is a check box, and it's important to have at least one (preferably 2+, from what I've heard.) She should be deliberate about leadership, both for the application and for the interview process. Is she a team captain (can she become one)? Can she organize something? Really, truly--what makes her a great leader? Dig deep. Not all of it will be resume worthy, but it can help factor into interviews for nominations, etc.
Feel free to PM me if you have any questions.
