About JAG Endoscopy Training System (JETS)

JETS supports high-quality and standardised endoscopy training in the UK by offering training courses for endoscopists and an ePortfolio for trainees to record their procedure data. 

Who is the programme aimed for?

JETS is an online ePortfolio and certification portal for trainee endoscopists (doctors and nurse endoscopists), covering several endoscopy modalities including oesophago-gastro-duodenoscopy (OGD), colonoscopy, flexible sigmoidoscopy, endoscopic retrograde cholangio pancreatography (ERCP), endoscopic ultrasound (EUS), and device assisted enteroscopy (DAE). 

Trainees can work towards certification in these modalities by recording their procedure data. The JETS system certifies trainees to undertake endoscopic procedures. 

Certification is aimed at trainees and is not for those who are already independent endoscopists. 

Certification process

Trainees undergoing the JETS certification process will be expected to log their endoscopic experience and have a formative direct observation of procedural skills (DOPS) assessment completed on their ePortfolio. When the trainee has fulfilled the eligibility criteria, they will need to arrange a summative assessment, which can be completed through the relevant certification page on their JETS account. 

All applications will be for full JAG certification. Colon (provisional) is no longer JAG recognised. Even after achieving certification, JAG recommends that all trainees should continue to seek further training on dedicated training lists as part of their ongoing personal development.

The Benefits of JETS

Trainers and training leads

Trainees receive support from their trainers and training leads.

Trainers: Trainers on the JETS system can act as assessors for candidate's summative DOPS. A trainee's primary trainer or a trainer who has submitted an appraisal on the trainee within 12 months cannot assess on these summative DOPS. Direct Observation of Training Skills (DOTS) and Long-term evaluation of trainer skills (LETS) are both frameworks to provide and receive feedback on trainer skills. These can be added through the JETS website. 

Training leads: Each endoscopy service with trainees should have a training lead(s). They have further functionality, including being able to review the performance of independently practicing endoscopists to ensure that they are achieving key performance indicators (KPIs). The training lead’s summary screen also supports dedicated training list allocation meetings, monitoring the training received by trainees and several items on the training GRS.


All JAG approved courses take place at our training centres (locations approved by JAG to run JAG approved courses). Candidates can access the course booking page to find courses to register for.
