Hello there, dsouza-cj27.
I've got the information you need about the QuickBooks Desktop (QBDT) certification.
Please know that QBDT certification is currently unavailable for UK versions. Thus, it is already discontinued.
You may want to know more about the reasons behind this discontinuation by checking out this article: QuickBooks Desktop discontinuation support.
If you have any other questions about training and certification, don't hesitate to contact Community support. We're always available to assist you.
