The Early Childhood Care and Education Programme of the Childhood Development Initiative was a 2-year programme that was delivered by Tallaght West Childhood Development Initiative and targeted at children and their families in Tallaght West in Dublin, Ireland. The programme was evaluated between 2008 and 2011 by researchers at the Centre for Social and Educational Research, Dublin Institute of Technology and the Institute of Education, University of London.

The evaluation was designed as a cluster randomised trial, an experimental method by which social units or clusters (in this case, Early Years services) were randomly allocated to intervention or control groups. The research team used the following sources of information: standardised child assessments taken over time; child social/behavioural profiles completed by Early Years service/primary staff and parents; parental interviews; quality rating scales; Early Years practitioner focus groups; documentary analysis; and observation.

Data from the cluster randomised trial is available for further research in the Irish Social Science Data Archive (see link below).
