Update:  Starting May 1, 2022, Prometric will no longer require candidates or test center personnel to wear masks unless required to do so by building management or local government mandates.  In light of recent trends and mask mandate changes around the world, along with updated guidance from leading world health organizations, Prometric will not require masks to be worn in test centers, however they will continue to allow and encourage the wearing of masks regardless of mandate or vaccination status.

ABO & NCLE pioneered virtual reality questions and has gone even further, providing a fully-interactive ABO & NCLE Tutorial and Practice Exam Question Area!  Learn about the types of virtual reality questions available on the ABO-NCLE Practical Examinations and how to utilize the Lens Meter, Slit Lamp, and many other on-line virtual instruments utilized on the ABO & NCLE Practical Examinations.  Finally, please review the Practical Slideshow prepared especially to allow candidates to understand the functionality and type of questions for each item within the ABO and NCLE Practical Examinations.  Extensive familiarity with computers is not required, but use of a computer keyboard and mouse should be within the experience of all candidates.

The proctors at the exam sites are not expected to provide detailed assistance to candidates. It is not their responsibility to provide assistance on things such as navigating through the exam or resolving any misjudgments made by the candidate.  Candidates need to carefully read the on-screen messages in order to respond correctly.  Computer-based testing options include the ability to navigate forward and backward through the exam, mark items for further review and then review answered, unanswered and marked items.  Items must be reviewed or changed prior to the expiration time. Once an exam is ended, candidates cannot return to the questions. The examination screen contains a timer showing the time remaining for the current exam.  Questions left unanswered will be considered incorrect. When there are unanswered items, additional time will not be allowed for completion, nor will there be any refund of fees or credit toward future fees. 

For the calendar year 2019, the ABO Practical Examination first time test taker pass rates were 59.5%; the NCLE Practical Examination first time test taker pass rates were 67%.
