Scaling up is attracting a great deal of attention in the international health and development elds. Interest in this topic stems from the widespread concern that the visions implied in the Millennium Development Goals, the Platform for Action of the International Conference of Population and Development and other international summits are not being achieved as fast and eectively as intended. Current eorts need to be multiplied to meet the challenges of the 21st century. It is therefore not surprising that numerous eorts are underway to address the need for scaling up. One such initiative was the formation of ExpandNet, a global network that seeks to promote equitable access to quality care by ensuring the benets of successful health interventions are expanded to reach more people, more quickly and more sustainably. e network’s activities include the development of tools, advocacy, technical assistance, networking and research (www.expandnet.net). ExpandNet’s work on scaling up grows out of the development and testing of the World Health Organization’s (WHO’s) Strategic Approach to Strengthening Reproductive Health Policies and Programmes. The Strategic Approach is a three-stage process that countries can use to identify and prioritize their needs for reproductive health policy and programme development, test appropriate interventions to address priority needs and scale up successful initiatives. e approach is based on the understanding that scaling up rarely occurs automatically as is often assumed. It requires focused attention, strategic planning and management as well as resource allocation. e Strategic Approach promotes the idea that a focus on scaling up is required when assessing needs and priorities as well as in designing pilot interventions.
