MADISON, Wis. (AP) _ Gov. Scott Walker has signed a bill that would increase requirements for high school math and science classes students would have to take for graduation.

The bill raises 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 gives schools flexibility to award math and science credits to students in career and technical education programs.

The proposal comes as the state's school districts are implementing more rigorous academic requirements. It would also bring Wisconsin more in line with neighboring states.
