The Texas Board of Education makes its final decision on science textbooks for public schools this November.  A battle over content has been raging for years. 

In the past, any text books getting the board’s approval were the only ones to be funded by the state.  That law changed two years ago, but Texas Freedom Network President Kathy Miller says many district’s still follow the state’s lead.

“Most of these publishers are still eagerly seeking the 100 percent approval rating from the state board of education,” Miller says, “because that's really going to guarantee that they have the most competitive edge in this market.”

Conservative Christians on the review board have been pressing publishers to change some of the content on topics like evolution and climate change.  Miller says that’s understandable from a political point of view.

“Controlling what kids learn in public schools, from kindergarten to graduation, is a really, really good strategy,” she explains, “if you're trying to dictate the politics of a state.”

Texas buys so many textbooks from the publishers, it is very influential on the point of view presented in the books.
