The average American should be able to pass the immigration and naturalization test.
Narrowing down the pool I looked at stats for the average 40-year-old American taking the test.
The test is designed to assess a person’s knowledge of American history and government, as well as their ability to speak and understand English. The civics portion of the test consists of 100 questions, and applicants must answer 6 of them correctly in order to pass. The English portion of the test requires applicants to read, write, and speak basic English.
