AUSTIN (January 31, 2013)--Education leaders in the Texas Senate Thursday slammed a curriculum system used in 875 school districts across the state, saying it may promote anti-American values and stifle classroom flexibility.

CSCOPE is an electronic curriculum management system that offers Web-based lesson plans and exams designed to help teachers adhere to the state educational requirements.

It is now used in more than 70 percent of Texas school districts.

It’s designed to aid teachers while being flexible enough for them to alter its content to meet their individual needs, but some teachers have complained CSCOPE locks them into a rigid curriculum, and conservative activists say it promotes progressive ideology.

A string of witnesses before the Senate Education Committee raised those concerns repeatedly Thursday.
