ADIT December exams move to a new platform: check your computer now
The CIOT will deliver the December 2026 ADIT exams, and the November 2026 CTA and ATT exams, on a new platform, RM Assessment Master. It told course providers on Friday.
For remotely proctored exams, including ADIT, you will need to install a secure browser on your own computer before the day.
- A system requirements guide sets out which operating systems and browsers are supported, and the firewall settings to whitelist.
- The CIOT strongly recommends against using a corporate device. Past firewall problems mean a work laptop is at your own risk.
- The candidate guide will be published next week. A practice test and further guidance will follow.
Our advice: decide now which computer you will sit on, and make sure it is one you control. Find out more
