MADISON, Wis. (AP) – Gov. Scott Walker plans to sign a bill that would increase requirements for high school math and science classes students would have to take for graduation. Walker was scheduled to sign the measure Wednesday in Madison. The bill would increase the math and science requirement for graduation from two to three credits each. A computer science class could count as a math credit and an agricultural sciences course could count as a science credit. The measure also would give schools flexibility to award math and science credits to students who are in career and technical education programs. The proposal comes as the state’s school districts are implementing more rigorous academic requirements and it would also bring Wisconsin more in line with neighboring states.
