Frequently Asked Questions

For anyone currently eligible to take the ACS the five-year time period to successfully complete the ACS will begin on January 1, 2022. After January 1, 2022 eligibility for the ACS will require successful completion of the ACJ. When a participant passes the ACJ, the five year time period will start.
When the new eligibility requirements come into effect on January 1, 2022, you will no longer be able to register for the ACS unless you have received a passing grade on the ACJ. If you have already passed the ACS but have not passed the ACJ this will not affect your ACS result.
We cannot confirm the date of the first ACS to be offered in the NDEB clinic; however, we do not expect to be able to offer the ACS in our facility before June 2022. The clinic construction is underway, but we are aware that construction delays are not uncommon. When we are confident that the ACS can be run, we will provide examinees with the dates of exam sessions and registration instructions.
