The Pacific Educational Group (PEG), which claims to be "committed to achieving racial equity", reportedly tells schools that the curriculum should be adapted for black students.
The group also teaches schools that misbehaving black students should not be suspended or expelled, according to reports.
And teachers were apparently told to begin sentences with phrases such as "As a white man, I believe..."
Critics have hit out at PEG, which began its costly partnership with the St. Paul school district in Minnesota in 2010.
One website claimed that the group "packages and sells the concept of victimisation [of black students] for a very high price".
With "time-outs" replacing suspensions, some students have reportedly caused "chaos" because there are "no real consequences for their actions".
Teacher Becky McQueen said: "There are those that believe that by suspending kids we are building a pipeline to prison.
"I think we're telling these kids: 'You can assault somebody and we're gonna let you come back here'."
Another teacher said: "We have students who will spend an hour in the hallway just running and hiding from people, like it's a game for them.
"A lot of them know no one is going to stop them, so they just continue. Express.
Just how stoopid do you have to be in order not to predict the consequences of such ideological idiocy?
