The NAJ JET Essentials course is an important part of the induction and training provided to you at CW Sellors. You will study four topics - Diamonds, Gemstones, Hallmarking and Precious Metals (Gold, Platinum, Palladium and Silver), each of which will be presented as an online training course.

At the end of each module you will take a short quiz to test your learning. The pass mark is 100% but don't worry, you can take the tests as many times as you like until you achieve a pass. You will probably need to commit 10 to 15 hours to the course to really get the most out of it. This can be spent reading and reviewing the course material, talking to colleagues to check your knowledge and understanding and even doing your own personal research.

The JET Essentials course is the ideal first step to further qualifications and can be counted towards the NAJ JET Certificate.
