The Applying Science to Strengthen and Improve Systems (ASSIST) activity enhances the quality of service delivery in the health sector and the care of orphans and vulnerable children. It provides training on the “science of improvement” and builds improvement teams in high-volume facilities that track progress. The activity strengthens systems at national and county government levels to support the institutionalization of quality improvement in child protection and programs for vulnerable children, improving the welfare of children. The activity is guided by the National Health Sector Strategic Plan II and the Ministry of Labor Social Security and Services’ outlined priorities for improving quality of services.
