The handbook contains an exam application, total content outline, sample questions, suggested bibliography and test center locations.
A practice test consisting of 75 questions with a testing time of 2 hours taken over the Internet is available through Professional Testing Corporation.
The practice test is designed to provide individuals with an opportunity to experience taking a computerized exam, to review an example of the type of content included in the Certification Examination for Ophthalmic Registered Nurses, and to learn more about question format, style, and level of difficulty.
After completing the online practice test, participants will receive an instant score report showing test performance in each of the content areas. The score report does not provide correct answers or indicate which questions were answered correctly and incorrectly.
NOTE: Performance on the online practice test may differ from actual performance on the Certification Examination. Thus, there is no guarantee that taking this practice test will help you pass the Certification Examination. Participants may find it helpful to review content in any areas of weakness indicated on the score report prior to taking the Certification Examination.
Practice Test Registration Fee: $60 by credit card

"Often patients see CRNO on my badge and ask what it means. With pride and confidence I assure them that it means their eye nurse is educated, devoted, and by maintaining certification I keep current on issues relevant to their care." - ASORN member Juli Young, RN, CRNO
