Students can take advanced English, math, science and language courses.
Officials say taking high school classes early leaves more time for advanced classes in high school - a path that increases a student's chances of getting into the college of their choice.
There are some requirements. Parents must consult with their middle school student's counselor to ensure readiness for the advance courses.
"We are very pleased to be able to give our high-achieving middle school students a jump on earning college credit, plus the opportunity to avail themselves of a greater number of challenging courses and electives once they reach high school," said Interim Superintendent Hank Hurd. "We are convinced that this move will serve to better prepare our students for college and other postsecondary goals."
