The Case Management Partnership Initiative (CMPI) addresses chronic truancy by linking truant ninth graders and their families to social services and case management, along with regular interagency case management meetings. A pilot was conducted at Anacostia and Ballou High Schools in 2011-2012. The implementation evaluation found that the pilot program successfully implemented an interagency partnership and linked families to needed services, which likely improved family well-being. Whether this impacted truancy is not yet known. To reduce chronic truancy, the CMPI is a promising platform for additional program experimentation, including possible modifications to timing, eligibility criteria, and program components.
