Our granddaughter (who lives with us) is attending a three day a week private homeschool support program. The school is doing some VERY innovative things with the way it teaches. Kids who learn in non-traditional ways are thriving there. We use the other two days a week for art classes, and all day outdoor wilderness school and horse riding lessons; plus trips to museums and the zoo.
Our youngest son, after a bunch of problems in public school, went to a two day a week tutoring program. At age sixteen he passed his GED and went to a local community college. (I have to brag, he just got accepted into a PhD program at Berkeley).
