IANPHI's NPHI directors suggested the development of a peer-to-peer evaluation initiative, supported by an evaluation tool/questionnaire. The initiative and evaluation tool described herein were developed 2013-2014 by a team of senior experts from IANPHI institutes, led by the French National Institute for Public Health Surveillance (InVS/Institut de Veille Sanitaire1). Its purpose is to provide a practical way to support NPHI Directors in demonstrating their respective organization's accomplishments and in identifying areas for development and improvement.
