1960, declares Mississippi to be a right-to-work state (though several other states have similar provisions, this is one of only five such provisions included in a state Constitution). Article 8 Sections 201–212 discuss the State Board of Education, the State and county school board superintendents, and generally the establishment and maintenance of free public schools, including those for disabled students. Sections 205 and 207, as well as the later-added 213B, were later repealed: Section 207, which required schools to be racially segregated, was repealed on December 22, 1978, 24 years after the U.S. Supreme Court had ruled such laws in violation of the U.S. Constitution. Sections 213 and 213A discuss higher education. Article 9 Sections 214–222 discuss the Mississippi National Guard. Article 10 Sections 224 and 225 allow the State to require convicts to perform labor, either in state industries or by working on public roads or levees (but not to private contractors); Section 225 also granted the state the power to separate "white" and "black" convicts, however this power was later repealed. Section 226 prohibits any convicts in county jails from being hired outside the county. Section 223 was repealed in 1990. Article 11 Sections 227–239 generally discuss the creation of levee districts within the State.

Article 12 Sections 240–253 discuss matters related to voting. Section 214 required an elector to be a resident of the state and county for at least one year prior to an election, and six months resident within the municipality they desired to register to be an elector. These were later determined to be unconstitutional by a US Federal Circuit Court in Graham v. Waller, as they served no compelling state interest, and a 30-day residency requirement was instituted in the same judicial order on a temporary basis. Subsequent statutes passed by the legislature kept the 30 day residency requirement. Sections 241A, 243 and 244 were later repealed: all three were designed, in some part, to disenfranchise minority voters (241A required that a person be "of good moral character", 243 instituted a poll tax, and 244 instituted a literacy test, all of which have been ruled unconstitutional). Article 13 This article consists of only Section 254, which states how the State shall
