Ata Health supported the University of New Mexico (Project ECHO) and the U.S. CDC to design and implement five virtual communities of practice focused on building leadership and management skills among CDC country-based staff.  Ata Health was responsible for designing and executing the monitoring and evaluation plan, which included a theory of change, session-based polls, electronic surveys, interviews and focus group discussions. Sessions were held with representatives from over 50 countries across four continents. Ata Health utilized statistical methods for assessing the relationship between vCOP exposure and outcomes, to determine the effectiveness and impact of the initiative.
