Standard Evaluation Framework for weight management interventions

The aim of the Standard Evaluation Framework for weight management interventions is to support high quality, consistent evaluation of weight management interventions in order to increase the evidence base.

This SEF provides introductory guidance on the principles of evaluation, and lists ‘essential’ and ‘desirable’ criteria. Essential criteria are presented as the minimum recommended data for evaluating a weight management intervention. Desirable criteria are additional data that would enhance the evaluation. The supporting guidance describes why particular criteria have been categorised as essential or desirable, and provides further information on collecting data.

PHE will be evaluating the usefulness and impact of the SEF and this will be informed by both quantitative and qualitative data, including the experiences of people who have used the guidance. If you would like to be involved in this evaluation, or if you have any feedback, please contact


Measurement of diet and physical activity behaviours presents considerable challenges to evaluators. PHE has produced guidance on measuring diet and physical activity.
