It causes one to wonder how many schools Woodall and Gatti have visited, or if they even did a simple web search. Since at the end of their article they say that the schools follow all federal regulations, it appears their "research" falls far below par.
This article sounds like an almost exact replica of an article released in 2010. Funny how the only thing they added were some vague allegations and suspicions, yet not adding much research of their own.
You can find an article below that is based on years of actual research done by objective professors http://gulenandcharterschools.blogspot.com/2011/04/gulen-inspired-schools-promote-learning.html.
