This technical paper presents the monitoring and evaluation (M&E) mechanisms of the Sunflower Centers in the Republic of Korea (RoK), which are integrated one-stop service centres for SGBV survivors that provide efficient and professional medical, counselling, legal, and police investigation services. The M&E mechanisms, created in 2017, ensure that all Centers are aware of and comply with quality standards. The paper aims to support partner countries understand the various aspects of the M&E tools and mechanisms of RoK so that they may apply the learning points in a localized and contextualized way in their country.
