Mississippi Code Title 37. Education § 37-15-13

When any child qualified under the requirements of Section 37-15-9 shall apply or present himself for enrollment in or admission to the public schools of any school district of this state, the school board of such school district shall have the power and authority to designate the particular school or attendance center of the district in which such child shall be enrolled and which he shall attend; no enrollment of a child in a school shall be final or permanent until such designation shall be made by said school board. No child shall be entitled to attend any school or attendance center except that to which he has been assigned by the school board; however, the principal of a school or superintendent of the district may, in proper cases, permit a child to attend a school temporarily until a permanent assignment is made by the school board.
