About the Written Exam

The written exam is a multiple choice, computerized exam containing  51 multiple-choice, single answer questions.  The exam is only offered in English.  You will have 75 minutes to complete the examination. In addition to the number of examination items specified, a small number (five to ten) “pretest” questions may be administered to candidates during the examinations. These questions will not be scored. The administration of such non-scored experimental questions is an essential step in developing future examination's. You will receive your written exam results right away. To pass the test, your percentage score must be at least 75%.

Retakes: Candidates who do not pass the written exam may re-take the respective exam after a 3-month waiting period. The initial exam and re-test fees and application procedures are the same.  After 3 retakes you will be permitted 1 attempt per calendar year. You may take the exam online once,  but for all additional exams you are required to test at a testing center

Fees Expiration and Refunds Policies: The written exam fee is $175. Exam fees are non-refundable and an exam fee will expire after one year if the exam has not been taken.
