You can get support and advice in evaluating your own projects:

What Works Wellbeing have designed a practical guide for charities and social enterprises to help show how they improve health, education or employment. https://measure.whatworkswellbeing.org/

Other organisations may find their step by step guide helpful: https://whatworkswellbeing.org/about-wellbeing/how-to-measure-wellbeing/

If you want an outline of evaluation approaches in Arts and Health Willis Newsome have been running training and have detailed key approaches here: http://creativeandcredible.co.uk/category/resources/

The Culture Health and Wellbeing alliance have compiled these and other resources here.

NUS (National Union of Students) has a programme called Dissertations for Good enabling organisations to link up with students working on relevant dissertations and areas of student. There is a cost for this but as members of the Leeds Arts Health and Wellbeing Network we can look at listing opportunities together?
