Unfortunately JETS is a UK based training programme and is not currently available to trainees in Ireland.
You will be able to register for JETS and book JAG approved training courses via the JETS website, however JAG certification (and the ePortfolio functionality) is only available to UK based trainees.
If you were to move to the UK then the procedures numbers completed in Ireland could be counted towards the total procedure numbers. The other procedural criteria and DOPS requirements would need to be completed in the UK.
There have been discussions with national leads in Ireland regarding JETS and JAG certification being available in Ireland, but these conversations are only at an early stage and no decision or timelines have yet been discussed.
