When the JAG was formed in 1994, it was initially aimed at doctors in training. Much has changed since then and the JAG has developed greatly.

The JAG now includes and recognises:

• Greater emphasis on improved standards for training and education.
   
• Nurse endoscopists becoming a highly significant part of the workforce.
   
• Acceptance that high quality training can largely only take place in high quality units.
   
• Realisation that the impact of service cannot be removed from having an influence on training.
   
• Implementation of bowel cancer screening for the UK, for which JAG was asked to oversee quality of endoscopists and of endoscopy units.
   
• Implementation of unit accreditation across all sectors.
