To become a citizen of a given country, a passing grade on a citizen test is required. As there are many steps in a process to become a legal citizen of a given country, the final step is usually the passing of a citizen test. This test usually measures the knowledge of the individual on the history, principles, obligations, rights, and trivia about the country for which they hope to become a citizen. While the questions are straightforward in nature, they must be properly answered and a passing grade must be received before an individual can become a citizen of that given country.
