Info about AltSchool on SfKFiles site: http://www.sfkfiles.com/2013/10/dadinthefog-altschool.html . The main post is from 2013, but the comments are from 2013 - 2016.

(I have found sfkfiles.com quite useful in the past. On some occasions I can get better insight from there than from the more well-known sites like greatschools.org and k12.niche.com .)
