In an attempt to fill the knowledge gaps on the impact of care and support strategies for orphans and vulnerable children, MEASURE Evaluation is conducting targeted evaluations of five OVC programs in five unique settings, two in Kenya and three in Tanzania. The Jali Watoto program by Pact through SAWATA (Saidia Wazee Tanzania) Karagwe was selected as one of the five programs for the evaluation. The program addresses the needs of most vulnerable children by targeting, mobilizing and sensitizing communities to support most-vulnerable children (MVC) and their families. This case study was conducted to provide a detailed account of the operations of the Pact/Jali Watoto project in supporting OVC in Karagwe district, which will guide the development of questionnaires and other pre-data collection preparations that are needed for evaluating the program based on their objectives.
