The Louisiana literacy test was a 30-question, 10-minute exam that parish registrars used starting in 1964 to block Black residents from registering to vote. It had almost nothing to do with reading. The questions were spatial puzzles and logic traps written so ambiguously that any answer could be marked wrong, and a single wrong answer meant automatic failure. Registrars decided who had to take it, and registrars alone decided who passed. The Supreme Court struck it down in 1965, and Congress banned literacy tests nationwide that same year.
Where the Test Came From
Louisiana’s voter suppression framework began at the state constitutional convention of 1898, which was called to eliminate Black political power. The convention’s judiciary committee chair, Thomas Semmes, said the reason plainly: “We met here to establish the supremacy of the white race.” The constitution that came out of the convention imposed literacy and property requirements on prospective voters, then built in an escape hatch for white applicants.
That escape hatch was the grandfather clause. Any man whose father or grandfather had been eligible to vote before January 1, 1867 was exempted from the literacy and property requirements. Almost no Black men in Louisiana had voting rights before that date, so the exemption applied almost exclusively to white residents. Registration under the clause closed on September 1, 1898.
The effect was immediate. Louisiana’s registered Black voters fell from roughly 130,000 in 1896 to about 5,000 by 1900, then to 1,342 by 1904, and bottomed out at 897 by 1940. The Supreme Court struck down grandfather clauses in Guinn v. United States (1915), but by then the white voters grandfathered in were already permanently on the rolls, and the literacy and interpretation tests kept operating against Black applicants.
Who Actually Had to Take the Test
The test was not given to everyone. The instructions printed on the test itself said it was administered to “anyone who cannot prove a fifth grade education.”1Tennessee State Library and Archives. The State of Louisiana Literacy Test In practice, the registrar at the parish courthouse decided who needed to prove it. White applicants were routinely waved through. Black applicants were sent to the exam.
Even before the test, applicants had to clear other hurdles at the courthouse: exact birthplace, precise time at their current address, and proof of residency in the state, parish, and precinct. Applicants also needed a currently registered voter to formally vouch for their character. In parishes with almost no registered Black voters, finding a willing voucher was close to impossible, and the registrar could reject the application on that ground alone without ever handing over a test.
Two Different Tests
Louisiana used two testing instruments, and they are easy to confuse.
The older one was the interpretation test. Applicants had to read a section of the Louisiana or U.S. Constitution and explain it to the registrar’s satisfaction. The registrar picked the passage, chose whether the test would be oral or written, and decided on the spot whether the interpretation was “correct.” There was no answer key. A registrar could hand a white applicant a simple clause and accept any paraphrase, then hand a Black applicant a dense procedural section and reject a competent answer. This was the test the Supreme Court examined in Louisiana v. United States in 1965, finding it gave registrars “virtually uncontrolled discretion as to who should vote and who should not.”2Justia. Louisiana v. United States, 380 U.S. 145
As legal challenges to the interpretation test built up in the early 1960s, Louisiana introduced a new instrument in 1964: the citizenship test, better known today as the Louisiana literacy test. This is the version that has become infamous. It did not replace the interpretation test on the books. It operated alongside it.
What Was on the 1964 Test
The 1964 test had 30 questions and a 10-minute time limit, giving the applicant roughly 20 seconds per question. One wrong answer failed the whole test. The instructions said: “Do what you are told to do in each statement, nothing more, nothing less. Be careful as one wrong answer denotes failure of the test.”1Tennessee State Library and Archives. The State of Louisiana Literacy Test
The questions were not about reading or civics. They were traps. Some real examples:
- “Draw a line around the number or letter of this sentence.” Does “around” mean circle the number 1, circle the letter, or circle the entire sentence? The registrar decided.
- “Spell backwards, forwards.” Spell the word “backwards” in a forward direction, or spell the word “forwards” backward? Both readings are grammatically valid.
- “Print the word vote upside down, but in the correct order.” What is “correct order” when the word is already inverted?
- “Write right from the left to the right as you see it spelled here.” A sentence that uses “right” in two different senses.
- “Divide a vertical line in two equal parts by bisecting it with a curved horizontal line that is only straight at its spot bisection of the vertical.” A line cannot be both curved and straight at the point of bisection.
Other questions used perceptual tricks. Question 25 asked applicants to write what they read inside a triangle containing the phrase “Paris in the the spring.” People reading quickly miss the repeated “the,” write “Paris in the spring,” and fail for copying the text incorrectly. Question 6 asked the applicant to draw three circles “one inside (engulfed by) the other,” which could mean concentric circles or three circles each inside the next, and either reading could be rejected.1Tennessee State Library and Archives. The State of Louisiana Literacy Test
Every question had at least two plausible readings. The “correct” answer was whichever one the applicant did not pick.
How Registrars Controlled the Outcome
The registrar was proctor, grader, and final authority. No standardized answer key was published. No grading rubric was available for review. The registrar timed the test, often with a stopwatch, and applicants could not ask questions during the 10 minutes.
After the applicant turned in the test, the registrar graded each answer by whatever standard they picked. Responses could be marked wrong for handwriting, ink color, or perceived imprecision in drawing a shape. A line drawn “around” a word could be rejected because it was an oval instead of a perfect circle. The ambiguity built into the questions guaranteed a defensible reason to fail anyone.
The Supreme Court described the arrangement as one where registrars exercised “unbridled discretion without any objective standards to determine voting qualifications,” and found it was “part of a successful plan unlawfully to deprive Louisiana Negroes of their voting rights.”2Justia. Louisiana v. United States, 380 U.S. 145 Appeals at the local level went nowhere. The registrar’s decision was final, and meaningful challenges required federal litigation that individual applicants could rarely afford.
How the Test Ended
The legal foundation for Louisiana’s tests collapsed in 1965.
In March 1965, the Supreme Court unanimously affirmed a lower court ruling that the interpretation test violated the Fourteenth and Fifteenth Amendments. The Court enjoined it statewide. It also blocked use of the 1964 citizenship test in the 21 parishes where discriminatory use of the interpretation test had been proven, unless the state reregistered all voters in those parishes under uniform standards.2Justia. Louisiana v. United States, 380 U.S. 145
Five months later, Congress passed the Voting Rights Act. Section 4 immediately suspended literacy tests in states and counties where less than half the voting-age population had been registered or had voted in the 1964 presidential election. Louisiana was one of the original covered states, along with Alabama, Georgia, Mississippi, South Carolina, and Virginia.3National Archives. Voting Rights Act (1965) The definition of banned “tests or devices” was broad: any requirement that a person demonstrate the ability to read, write, or interpret material, prove educational achievement, show “good moral character,” or obtain a voucher from registered voters.4Office of the Law Revision Counsel. 52 U.S.C. 10501 – Application of Prohibition to Other States
Congress extended the suspension twice, then made the ban permanent and nationwide in 1975. It is now codified at 52 U.S.C. ยง 10501. No state can impose a literacy test, interpretation test, vouching requirement, or moral character evaluation as a condition of voter registration anywhere in the country.4Office of the Law Revision Counsel. 52 U.S.C. 10501 – Application of Prohibition to Other States
After decades in which fewer than 1,000 Black residents were registered to vote in Louisiana, registered Black voters in the state approached 400,000 by 1976.
