With Senate Bill 1031 in spring 2007, Texas legislators repealed TAKS in favor of End of Course exams in high school; however, this change will happen gradually. Students who enter ninth grade in the 2011-2012 school year will have to take end-of-course exams in core subjects. Students who entered ninth grade before 2011 will still have to pass the exit-level TAKS to graduate. A calendar which shows the field test and implementation schedule has been developed.
According to the Texas Federation of Teachers, the EOC will require students taking either the Recommended or Advanced curriculum to take three end-of-course exams in each of four core subjects: English I, English II, English III; Algebra I, Algebra II, Geometry; Biology, Chemistry, Physics; World Geography, World History, U.S. History.
