Dr Claire Noble and the Story Starters team at the University of Liverpool have developed a new video explaining the impacts and benefits of evaluating interventions. It covers how interventions work, why it is important to evaluate interventions and describes a 'gold standard' kind of evaluation known as a Randomised Controlled Trial (RCT). Watch the full video here or read the transcript of the video. This work is part of a larger project to improve the evidence base on what works in early years interventions for promoting communication and language development. You can find out more about this work on our evaluation page.
