The Deseret News in Salt Lake City published a nine page article that I found to be totally engrossing. You can read it here.  A charter school was set up as just another charter school, but with an international focus.  Over time the American teachers noticed that more and more Turkish men were being hired as teachers and flown into the country.  The governing board was almost entirely made up of Turkish men and they voted in a block.  American teachers were getting passed over for promotions.

A lengthy investigation, performed by American teachers who just wanted to know what was going on, showed that dozens of schools were all connected to a single Turkish Islamic preacher.

Wow, what an amazing web they had to navigate.  I recommend you read it.
