You would need to discuss this with Creative Head office and thereofre the best thing to do is give them a call - it depends on whether the course you did is a recognised course by them or not, and also the length of time since you did it. For example I know they do recognise NVQ and VTCT, but don't recognise Essential Nails. I converted to Creative L&P from my inital training with Bio Sculpture gel, but I needed to do some 1-2-1 with Creative first to cover basic product application, as they recognised I understood Health and Safety, and Nail anatomy, but hadn't covered the basic product stuff.
It has caused healthy debate in the past, but any company needs to set its rules, so most folks appreciate that. And I can also honestly say that the 1-2-1 training was probably the best money I have spent in my entire nails career.
