Iolani/Punahou parents who homeschooled pre-k

I am curious what parents who did not preschool/tutor (juku) their kids do for recommendations on the Iolani/Punahou application.

If your child(ren) were accepted at either, what/who did you use for your recommendation letter?

I know the generic 'Someone who observed your child in such and such scenarios', but I'd like to know if anyone has been successful outside of the traditional pre-k and tutoring methods touted online. Whether it's been via Music/Dance/Swimming teachers or another approach...

Thanks for any insight!
