This article presents Estonia's initial experiences of implementing its National Action Plan (NAP) on Women, Peace and Security (WPS) and identifies best practices and lessons identified during the process. The achievements of Estonia's first National Action Plan (2010–2014) are examined to provide an overview of the current NAP objectives for the years 2015 to 2019. The article analyses Estonia's NAP in the light of four basic elements that should ensure successful strategic implementation: levels of commitment from the institutions responsible, concrete measures that have been taken to achieve the NAP's set goals, the budget dedicated to the plan, and responsibility and monitoring mechanisms. In addition, this review identifies current issues on the national level that need greater attention if Estonia is to move closer to achieving the goals set by the United Nations Security Council's Resolution 1325.
