How do we know if an intervention is effective?

In this step, Dr Calum Davey introduces impact evaluations. Impact evaluations are an increasingly common part of evidence-based programming for persons with and without disabilities. An impact evaluation is using data and research design to work out what effect a programme, policy, or other intervention has had on outcomes we are interested in.

Dr Davey is an Assistant Professor at the International Centre for Evidence in Disability.
