The Tanzania Para Social Work Program represents a comprehensive workforce development model to strengthen the social welfare system in low-resource countries. The program was developed to equip caregivers and their supervisors with critical knowledge and skills that strengthen their ability to provide care and support to vulnerable children and their families, particularly in communities most affected by HIV/AIDS. This training manual and curriculum containing seven chapters introduces Para Social Workers to the basic concepts, processes, and helping skills that underlie all interventions with children and families, thus providing a foundation for effective intervention with this population.
