Enrollment in the Indiana school voucher program, the nation’s largest, has more than doubled since last year.The Indiana Department of Education says more than 9,300 families have signed up for vouchers for the 2012-2013 school year. That compares with about 3,900 who took part in the program's first year.Families that take part in the School Choice Scholarship Program receive tax money to help pay the cost of private school. Under the program, vouchers can cover up to 90 percent of the cost of tuition, depending on a family's income. The actual value of the vouchers is less than the amount of tax money a public school would have received for that student.The maximum value for students in grades one through eight is $4,500.The Indiana Supreme Court will hear oral arguments in a legal challenge to the voucher program Wednesday morning.
