The IASC Gender with Age Marker (GAM) looks at the extent to which essential programming actions address gender- and age-related differences in humanitarian response.   It was developed in response to requests to strengthen the original IASC Gender Marker by including age and, most significantly, by adding a monitoring component.  In addition to providing an expanded tool to measure programme effectiveness, it is a valuable teaching and self-monitoring tool, allowing agencies and partners to learn by doing in the process of enhancing effective programming that is responsive to all aspects of diversity. GAM Overview
