La. R.S. 17:151.1

Any city or parish school board may, with the approval of the State Board of Elementary and Secondary Education, and with the approval of the Board of Regents or its successor, extend the curriculum of any high school established within its jurisdiction to include a thirteenth or fourteenth grade, or both, when, by a decision of the local school board, such extension is necessary or desirable for the benefit of school children within its jurisdiction. In such instances, these city and parish school boards shall designate appropriate courses of study to be offered in the additional school grades so established and shall provide the facilities necessary for the effective operation of such an extended school program. The awarding of any degree, diploma, or certificate for successful completion of a course of study offered in the additional school grades shall be subject to approval, disapproval, or modification by the Board of Regents or its successor.
