It is developed by Classic Learning Initiatives. But the company doesn't have its own wikipedia page, despite clearly having written this page. The only name listed is the "creator" of the CLT Jeremy Tate; who also doesn't have his own Wikipedia page.
Tate, the founder and CEO of CLT said the College Board has “censored the entire Christian-Catholic intellectual tradition” and other “thinkers in the history of Western thought.”.
They're hard-core Catholics trying to look generic Christian so they don't scare off the Evangelicals but also not so Christian they scare off the secular completely either.
