This evaluation of the Case Management Partnership Initiative (CPMI) found that the program successfully linked high-need families with services designed to prevent truancy. The truancy prevention program, implemented at Anacostia and Ballou High Schools in 2011-2012, links chronically truant ninth graders and their families to social services and case management, and includes weekly interagency case management meetings. While the evaluation found that the program was implemented as intended, it is unclear whether the program's efforts impacted truancy among participants. Nonetheless, CMPI remains a promising platform for additional program experimentation, including possible modifications to timing, eligibility criteria, and program components.
