Narrowing the Gap (NtG) is a two-year development and research programme, funded by the Department for Children, Schools and Families (DCSF) and the Local Government Association (LGA), working in partnership with other agencies, including local authorities. It seeks to make a significant difference, on a national scale, to the performance of Children's Trust arrangements in "narrowing the gap" in outcomes between "vulnerable" children and the rest. This current report is the third in a series and provides both a progress report and updated information related to the two main aims of the study: (1) To secure and undertake a review of any further data available on vulnerable groups from smaller and more varied national, regional and local sources in order to establish whether a better estimate can be made of the size, characteristics and factors that influence the ECM outcomes for vulnerable groups; and (2) To secure and extract pertinent qualitative evidence on the best ways of redressing disadvantage from recent evaluations of specific programmes and interventions which have focused on improving outcomes for different vulnerable groups. Appendix A provides further details on the scope, extent, focus, periodicity and reporting schedules of each of these studies. Appendix B provides an overview of the commissioners and contractors of the research; the focus, methodologies and research aims of the studies, along with reporting schedules (where known); and the vulnerable groups and ECM outcomes to which they relate (or may relate).
