As JETS is a UK based training programme trainees can only become accredited if they are currently working in the UK. In order to become certified all criteria will be need to met; unfortunately there are no shortcuts in this regard.
However, trainees are able to include procedures performed in other countries by adding it to their portfolio through the 'Baseline' tab. This will then be included in the lifetime procedure data.
Instructions on how to upload procedures performed in other countries can be found here.
