Certified Nephrology Nurse (CNN) Practice Exam


The purpose of this test is to allow eligible candidates for the CNN examination to practice with a test similar in content and format developed using the same process as that used in the actual CNN test development. However, no questions on the CNN practice exam will be on the actual CNN exam.

The CNN practice exam contains 50 questions and has 90-minute time limit. The fee for the exam is $50. All questions should be answered; you will not be penalized for guessing. Once the CNN practice exam is completed, all questions and rationale for the correct response will be displayed for review. The actual CNN exam contains 200 questions and must be completed in four (4) hours (150 questions in three [3] hours for the CBT exam) and requires a correct response rate of between 70 and 75% to pass the exam, depending on the version of the test. Performance on the CNN practice exam does not guarantee a similar performance on the CNN exam.

Your credit card payment will be processed on-line and you will be granted immediate access to the CNN Practice Exam. When entering the CNN Practice Exam, the examinee will be presented with one question at a time with four responses to choose from. The examinee should select the single best response to that question and then select “NEXT” to save that answer and move to the next question, while still having the ability to come back to that question for further review.

When all questions are completed, the examinee should then choose to “END”. You will be presented with a “Test Summary” indicating which items have responses and which do not. When you are satisfied with your responses, select “Submit test”. A score will be given and each question with the selected response and rationale will be displayed. If you choose to take the exam at another time (for the same fee), the experience will vary but the questions will be the same.
