Mississippi Code Title 37. Education § 37-7-339

(1) The school board of any local school district, in its discretion, may provide extended day and extended school year programs for kindergarten or compulsory-school-age students, or both, and may expend any funds for these purposes which are available from sources other than the adequate education program. It is not the intent of the Legislature, in enacting this section, to interfere with the Headstart program. School boards, in their discretion, may charge participants a reasonable fee for such programs.

(2) The school board of any school district may adopt any orders, policies, rules or regulations with respect to instruction within that school district for which no specific provision has been made by general law and which are not inconsistent with the Mississippi Constitution of 1890, the Mississippi Code of 1972, or any order, policy, rule or regulation of the State Board of Education; those school boards also may alter, modify and repeal any orders, policies, rules or regulations enacted under this subsection. Any such program pertaining to reading must further the goal that Mississippi students will demonstrate a growing proficiency in reading and will reach or exceed the national average within the next decade.
