Coverage Monitoring Network – Coverage Toolkit

October 24, 2014

One of the most important elements behind the success of the Community-Based Management of Acute Malnutrition (CMAM) model of service delivery is its proven capacity for achieving and sustaining high levels of coverage over wide areas.

Two-stage cluster sampled surveys have been used to estimate the coverage of selective feeding programs. This approach suffers from several important limitations. In response, Valid International, Concern Worldwide, and the Food and Nutrition Technical Assistance Project (FANTA) developed a new survey method for estimating the coverage of selective feeding programs. This survey method, known as the Centric Systematic Area Sampling (CSAS) method, uses a combination of stratified and systematic area sampling and active and adaptive case-finding.

The CSAS survey method provides a rich set of information about program coverage. In particular, it provides a ‘headline’ estimate of overall program coverage, a map of the spatial distribution of program coverage, and a ranked list of program-specific barriers to service access and uptake.
