The Missouri Civics Education Initiative, passed by the Missouri legislature and signed by Governor Nixon in June 2016, requires any student entering 9^th grade after July 1, 2017 to pass an examination on the provisions and principles of American civics.

The law states that the examination shall consist of 100 multiple choice questions similar to the one hundred questions used by the United States Citizenship and Immigration Services (USCIS) and may be included in any other examination that is administered on the provisions and principles of the United States and the State of Missouri, and in American history and American institutions. The full text of the law can be found at http://www.senate.mo.gov/16info/pdf-bill/tat/SB638.pdf.

Translation: you have to pass this test with at least a 60% score in order to earn a high school diploma in the state of Missouri.

You may take the test as many times as needed but must be passing by September 20th.
A list of testable items is available through U.S. Citizenship & Services. The questions you will be answering are the same questions provided to prospective U.S. citizens. The following are some other resources available:
