<p><p>From April 2004, a set of Government policies designed to help lone parents into work have been piloted in various combinations in a number of Jobcentre Plus districts in Great Britain. The five policies are: In Work Credit (IWC), Work Search Premium (WSP), Extended Schools Childcare (ESC) and Childcare Tasters, Quarterly Work Focused Interviews (QWFIs) for lone parents whose youngest child is aged 12 or over in Local Education Authorities (LEAs) in which an ESC pilot is operating (ESQWFI), and New Deal Plus for Lone Parents (ND+fLP), hereafter collectively referred to as 'the lone parent pilots' (LPPs or 'the pilots'). The pilots were rolled out in four Phases, the first three of which are analysed in this report. </p><p>This report estimates the impact of the LPPs on lone parents who have received Income Support (IS) or Jobseeker's Allowance (JSA) for at least 12 months. It uses a difference-in-differences (DiD) estimator, and makes use of lone parents in districts not operating a pilot as a comparison group. The data covers the first 12 months (Phase 3 districts) to the first 24 months (Phase 1 districts) of the pilots' operation, and so should be seen as giving the early impacts. Impacts were estimated separately for the stock of lone parents who had been on benefit for at least 12 months when the pilots began, and the flow sample of lone parents whose claim of IS/JSA reached 12 months after the pilots began.</p></p>
