Uganda’s laws, policies and health sector strategies codify openings for in planning and monitoring government services, yet these spaces are often inaccessible in practice. In response to this, a consortium of civil society organizations led by GOAL designed and implemented the Accountability Can Transform Health (ACT Health) program in Uganda from 2012 to 2018. This paper draws on program monitoring data, empirical evidence, and supplementary interviews to analyze how and the extent to which the ACT Health multi-level, people-centered advocacy campaigns strengthened accountability for health from the bottom up.
