ADC - Testing your ADC access

Modified on Fri, 7 Aug at 2:14 PM

Your ADC is administered using live video conferencing via Microsoft Teams and the Government Commercial College (GCC) platform. 


To complete the ADC you will need:

  • Laptop or desktop computer, including webcam - due to issues concerning compatibility we do not recommend completing the ADC using mobile or tablet devices. Unfortunately, the ADC team cannot provide a device for you to complete your ADC sitting. If you do not have access to a laptop or desktop computer, please let us know by emailing gcfdevelopmentcentre@cabinetoffice.gov.uk.

  • Reliable internet connection - you can use a speed tester provided by Ookla. If your internet download speed is below 5Mbps, this may mean you will struggle to access Teams or the GCC.

  • Google Chrome browser - the GCC is best optimised on Google Chrome. While you may use alternative browsers (Safari, Microsoft Edge, Firefox etc), there is no guarantee that they will provide the best user experience. You can test your browser's optimisation by completing our demonstration exercise, instructions for which are included in your ADC Joining Instructions.

  • GCC access - after receiving your joining instructions, you should be able to log in to the GCC and view the course page. Please let us know if you are having any issues by emailing gcfdevelopmentcentre@cabinetoffice.gov.uk.


We recommend you test each of these requirements before your ADC date, to ensure you’re fully prepared for the day.


Some government-issued devices contain software that prevent access to certain programmes. You should check with your department’s IT service to make sure you are able to access all required areas of the ADC.


If you are unsure whether your equipment, Teams, or GCC access will work, an access test can be arranged with a member of our team. If you are interested, please contact us by emailing gcfdevelopmentcentre@cabinetoffice.gov.uk.
