A literacy test assesses a person's literacy skills: their ability to read and write. Literacy tests have been administered by various governments, particularly to immigrants. In the US, between the 1850s and 1960s, literacy tests administered to voters had the effect of disenfranchising African Americans and other groups with diminished access to education. Other countries, notably Australia, as part of its White Australia policy, and South Africa adopted literacy tests either to exclude certain racialized groups from voting or to prevent them from immigrating.
From the 1890s to the 1960s, many state governments administered literacy tests to prospective voters, to test their literacy in order to vote. The first state to establish literacy tests in the United States was Connecticut.
State legislatures employed literacy tests as part of the voter registration process starting in the late 19th century. Literacy tests, along with poll taxes, residency and property restrictions, and extra-legal activities (violence and intimidation)[better source needed] were all used to deny suffrage to African Americans.
The first formal voter literacy tests were introduced in 1890. At first, whites were generally exempted from the literacy test if they meet alternate requirements that in practice excluded blacks, such as a grandfather clause, or a finding of "good moral character", the latter's testimony of which was often asked only of white people, many of whom, especially most post-Civil War Southerners, were against any non-whites' voting rights.
In Lassiter v. Northampton County Board of Elections (1959), the U.S. Supreme Court held that literacy tests were not necessarily violations of Equal Protection Clause of the Fourteenth Amendment nor of the Fifteenth Amendment. Southern states abandoned the literacy test only when forced to do so by federal legislation in the 1960s. The Civil Rights Act of 1964 stated that literacy tests used as a qualification for voting in federal elections be administered wholly in writing and only to persons who had completed at least six years of formal education.
To curtail the use of literacy tests, Congress enacted the Voting Rights Act of 1965. The Act prohibited jurisdictions from administering literacy tests, among other measures, to citizens who attained a sixth-grade education in an American school in which the predominant language was Spanish, such as schools in Puerto Rico. The Supreme Court upheld this provision in Katzenbach v. Morgan (1966). Although the Court had earlier held in Lassiter that literacy tests did not violate the Fourteenth Amendment, in Morgan the Court held that Congress could enforce Fourteenth Amendment rights—such as the right to vote—by prohibiting conduct it deemed to interfere with such rights, even if that conduct may not be independently unconstitutional.
As originally enacted, the Voting Rights Act also suspended the use of literacy tests in all jurisdictions in which less than 50% of voting-age residents were registered as of November 1, 1964, or had voted in the 1964 presidential election. Congress amended the Act in 1970 and expanded the ban on literacy tests to the entire country. The Supreme Court then upheld the ban as constitutional in Oregon v. Mitchell (1970), but just for federal elections. The Court was deeply divided in this case, and a majority of justices did not agree on a rationale for the holding.
The literacy test was a device to restrict the total number of immigrants while not offending the large element of ethnic voters. The "old" immigration (British, Dutch, Irish, German, Scandinavian) had fallen off and was replaced by a "new" immigration from Italy, Russia and other points in Southern and eastern Europe. The "old" immigrants were voters and strongly approved of restricting the "new" immigrants. The 1896 Republican platform called for a literacy test.
The American Federation of Labor took the lead in promoting literacy tests that would exclude illiterate immigrants, primarily from Southern and Eastern Europe.
Corporate industry however, needed workers for its mines and factories and opposed any restrictions on immigration. In 1906, the House Speaker Joseph Gurney Cannon, a conservative Republican, worked aggressively to defeat a proposed literacy test for immigrants. A product of the western frontier, Cannon felt that moral probity was the only acceptable test for the quality of an immigrant. He worked with Secretary of State Elihu Root and President Theodore Roosevelt to set up the "Dillingham Commission," a blue ribbon body of experts that produced a 41-volume study of immigration. The Commission recommended a literacy test and the possibility of annual quotas. Presidents Cleveland and Taft vetoed literacy tests in 1897 and 1913. President Wilson did the same in 1915 and 1917, but the test was passed over Wilson's second veto.
