Unusually for a UKCRC registered trials unit we also support and lead randomised controlled trials and other rigorous evaluations in the social sciences: particularly education. We host an annual international conference of randomised trials in the social sciences. We have worked with the Behavioural Insights Team (‘Nudge Unit’), where we have collaborated writing a policy paper on encouraging the use of RCTs across government (the paper can be viewed on the government website). Catherine Hewitt is also a member of the team providing advice and support to undertake trials within Government. We have received funding to support these studies from a range of sources including the Department for Education. However, our primary funding source is the Education Endowment Foundation (EEF). Our research has informed a number of educational policies and we have supported the methodological development of RCTs in education. (The introductory handbook can be found on the EEF webpage). Our expertise in non-health trials enhances our support of health related studies that are in a non-health setting. For example, the CONNECT study of training Police Officers in mental health issues, the BRIGHT trial of dental hygiene among school children and the GATEWAY trial of improving the mental health of offenders and reducing the risk of reoffending.
