The Canadian Citizenship Test is a test, administered by the department of Immigration, Refugees and Citizenship, that is required for all applicants for Canadian citizenship who are aged between 18 and 54 and who meet the basic requirements for citizenship. The test is available in both French and English, the official languages of Canada. The test is usually written, but in some cases it might be oral and take place in the form of an interview with a citizenship officer. The Department of Immigration, Refugees and Citizenship decides if the applicant's test is written or oral, depending on their various criteria. The test lasts for 45 minutes and contains 20 true or false or multiple choice questions. Applicants for citizenship must answer at least 15 (75%) questions correctly to pass the test. Applicants must be in Canada when taking the test and must take the test within 21 days of receiving an invitation.
