From Robert Marus: Mayor Vincent C. Gray joined leaders from the government, private, philanthropic and non-profit sectors today in unveiling Raise DC, the District’s comprehensive new cradle-to-career initiative. The effort, which lays out a set of measurable outcomes and targets to ensure that all District youth are career-ready by age 24, joins a national movement of cities working to bring together a cross-sector group of leaders organized around a set of common goals and committed to using data to drive improvements.
