Pennsylvania Gov. Tom Wolf (D) announced on Wednesday that he will sign a bill requiring students in the state to take a test on civics.

The bill, which the Pennsylvania state House passed overwhelmingly on Wednesday, will require students in grades seven through 12 to take a test on U.S. history, government and civics, The Associated Press reported.

Students will not have to pass the test in order to graduate. However, those who earn a perfect score will qualify for a certificate from the state’s Education Department.

Schools will be mandated to report how many students passed the test. The exam itself will be locally created, according to the AP.

Supporters of the measure claim that many American adults don’t have a strong understanding of civics.

Several states passed laws last year stating that graduating seniors should pass the civics test administered to immigrants in order to earn citizenship, in response to President Trump’s immigration crackdown.
