HARTFORD, CT -- In a time of uncertainty, leaders in Hartford public schools, nonprofit agencies and the philanthropic sector say they are committed to the city’s “community school” strategy that has been cited as a national model. On Wednesday, members of the Hartford Partnership for Student Success, a coalition that includes public and private partners, signed another yearlong agreement to continue the decade-old “wraparound” help that has turned a half-dozen city schools into neighborhood hubs with health services, after-school programs, clothing banks and holiday dinners. The Hartford Partnership for Student Success is supported by the Hartford Foundation for Public Giving, Hartford Public Schools, the Office for Youth Services, and the United Way of Central and Northeastern Connecticut.
