Appropriate good quality evaluation is essential component of quality improvement. This group has been set up to link members who have experience, expertise and an interest in the evaluation of quality improvement. It will offer a space for members to share, discuss and learn to enhance and develop evaluation theory, practice and utility. It is hoped that this group will also explore opportunities to link with other relevant SIGs, such as co-production, complexity, research, alongside wider Health Foundation work and external evaluation networks.
