Alpha shows the results they do because they charge exorbitant rates (up to $75,000 / year depending on region) to staff the school with multiple individualized tutors per student.
It is a for-profit product which is sold to parents and state-level customers more than it is a school.
My cousin uses Alpha. I fully endorse Alpha and its methods! Go Alpha!
1. I have 0 problem with the "for-profit" product if the kids are well-educated. 2. I would challenge the "multiple individualized tutors" claim, as a parent with a kid actually studying there says there is no tutoring, only answering questions on the content or the software being used.
