From The Greenville News: South Carolina Gov. Nikki Haley has signed into law a bill expanding charter schools. The new law allows boys-only and girls-only charter schools and requires traditional schools to open their doors for students who want to do extracurricular activities not offered by their charter schools. It also allows universities to sponsor their own schools. South Carolina has 17,000 students in 47 charter schools. Eight more charter schools are scheduled to open before the end of 2012, and many other planning groups are considering opening their own charter schools.
