This report is a summary document which explains the rationale for the CECIL (Coaching Early Conversations Interaction and Language) project, delivery within the context of COVID-19, the findings, the learnings, and next steps. The Institute for Employment Studies (IES) led an Implementation and Process Evaluation (IPE), and the University of Oxford led an Impact Evaluation. CECIL is a mixed-method research project that aims to provide high quality provision for children in Early Years settings to enable them to develop strong communication and language skills. The mechanism for support is continuing, professional development (CPD) to develop, embed, and sustain effective practice amongst practitioners working in Private, Voluntary and Independent (PVI) settings in areas of disadvantage.
