Anyone applying for citizenship through naturalization will face a more challenging test starting in December.

The U.S. Citizenship and Immigration Services (USCIS) announced Friday a revised version of the citizenship civics test for naturalization applicants, who must prove they can read, write, and speak basic English, while also having a basic understanding of the history of the U.S. and its government, according to a news release. 

Plans to revise the naturalization test were originally announced in July 2019. 

“USCIS has diligently worked on revising the naturalization test since 2018, relying on input from experts in the field of adult education to ensure that this process is fair and transparent,” said USCIS Deputy Director for Policy Joseph Edlow in the release.

“Naturalization allows immigrants to become fully vested members of American society, with the same rights and responsibilities as citizens by birth, and offering a fair test, which prepares naturalization applicants for these responsibilities, is of upmost importance to our agency.”

The revised version of the test will include more questions about U.S. history and civics, although applicants still only need to score 60% or better to pass.
