LINCOLN, Neb. (AP) — Nebraska could require high school students to pass the federal government’s civics exam for United States citizenship if a bill in the Legislature becomes law.

Sen. Bob Krist of Omaha introduced a measure Monday that would require students to answer at least 70 percent of the test’s questions correctly before they graduate. If passed, the bill would go into effect during the 2017 school year.

The Joe Foss Institute, a civic education group that champions the measure, says nine states have passed similar laws. The other states are Idaho, Utah, Arizona, North Dakota, South Dakota, Louisiana, Wisconsin, Tennessee and South Carolina.
