LISC engaged Community Science to evaluate its Community Building Initiative, which involved 30 Community Development Corporations (CDCs) across the country. The CBI was intended to improve the CDCs’ capacity to go beyond “bricks and mortar” and to improve their communities’ social development. Community Science interviewed national and local LISC staff, reviewed progress reports submitted by local LISC offices to the national LISC office, and conducted annual site visits. The final evaluation report shed light on the strengths and limitations of the local LISC officers to engage in social development and community building beyond their more traditional role of housing development.
