Why This Program?

The course offerings in this certificate program are designed to meet the educational needs of those engaged in implementing nutrition-related programs around the world; build the capacity of practitioners through specialized, graduate level, pre-service or in-service training in program delivery science; and provide the opportunity to engage in lifelong professional development and networking.

Students will gain a broad understanding of the issues inherent in designing, developing, and implementing nutrition intervention programs with an emphasis on developing countries; learn to differentiate between various health and nutrition theories and models in order to apply them appropriately to scenarios they face in their current work; and apply proven methodologies to design, monitor and evaluate interventions and educational health and nutrition programs.

The Delivery Science in International Nutrition certificate is conferred jointly by the Tufts Friedman School and partner institution, United Nations University (UNU). The mission of the UNU is to contribute, through research and capacity building, to efforts to resolve the pressing global problems that are the concern of the UN, its Peoples and Member States. A part of that contribution is to develop educative opportunities for UN personnel and other related non-governmental organization (NGO) member organizations who work closely with the UN in various capacities. Tufts University, being an affiliated institution, is charged with helping to carry out this educative mission by developing and implementing educational programs, particularly in the area of nutrition and capacity building, for UNU’s staff and NGO employees worldwide.

The Delivery Science for International Nutrition Certificate program consists of the following three courses:

  • Program Development and Delivery (Offered Fall Semester)
    This course provides presentations, readings, and exercises relating to the broad range of nutrition interventions utilized in global programs, including: growth monitoring and promotion; nutrition counseling and IEC; supplementary feedings and food-based income transfers; household food security and agricultural-based interventions; micronutrient activities; and breast-feeding.The course covers malnutrition causality, nutrition and structural adjustment, social funds, economic and food aid, active learning capacity and the nutrition transition. Students become versed in program design and appraisal techniques including dynamic models and program contraint assessments, and are responsible for major exercises relating to programs in Asia, Africa and Latin America.
  • Theories of Behavior Change and an Introduction to the Positive Deviance Approach (Offered Spring Semester)
    How do you achieve behavior change in challenging circumstances? This course explores that question, first by examining theories of behavior change commonly used in nutrition and public health and then with an in-depth introduction specifically to the Positive Deviance Approach. In the first half, several individual-based, social-based, organization-based and eco-social theories will be explored, with an emphasis on understanding of core theory concepts and issues in measurement. Building on this base, the second half will cover the concept, theory, history and application of PD. Students will develop their own problem statement and map out the steps required to apply the PD approach to their identified problem. By the end of this course, students will understand the steps involved in the PD process, acquire basic skills to complete step one of the PD process, and develop a proposal to design a PD inspired project plan. Interactive activities and assignments will teach students when to apply each of the behavior change methods.
  • Monitoring and Evaluation (Offered Summer Semester)
    This course provides an introduction to the principles and practices of program monitoring and evaluation, as applied to food security and nutrition-related programs in developing countries.  The course content will be imparted through online lectures, case studies, interactive discussion, and assignments that prompt students to grapple with monitoring and evaluation challenges facing ongoing global efforts to combat malnutrition and food insecurity.  By the end of the semester, course participants will: be familiar with the strategies and techniques for monitoring and evaluating projects, particularly those related to nutrition and food security; be able to assess the adequacy of monitoring and evaluation proposals and program evaluations designed by others; be exposed to multiple domestic and international examples of monitoring and evaluation systems, both large and small; and gain experience in the design of monitoring and evaluation plans for real programs.
