Mississippi Code Title 37. Education § 37-13-19

In addition to the curriculum otherwise required by law or the State Board of Education to be taught in the public schools of this state, the school board of a local school district may allow course credit to any high school student, who is a member of the National Guard and attends basic training camp during the summer between the end of the student's junior year and the start of the student's senior year of academic instruction. At the conclusion of the student's basic training, the commanding officer of the National Guard unit of which the student is a reserve member shall provide evidence of the student's completion of training to the local school district where the student is in attendance. Upon receipt of the evidence provided by the National Guard, the school district may award one (1) Carnegie unit of elective credit to the student. This elective credit may be applied along with the total number of Carnegie units required for the student to graduate.
