You may be aware that NIHR and Health and Care Research Wales have been working on producing a set of standards for public involvement. The draft version is now open for consultation. On this page https://sites.google.com/nihr.ac.uk/pi-standards/consultation you will find the standards and a copy of the online survey through which they are asking for feedback to be submitted. They suggest that if you are responding from a group, it would be better to discuss the standards and decide on responses (they have created some slides and guidance to help with this) and then just one person submit them through the survey. Individual responses are welcome too though.
