Gender mainstreaming has become an area of expertise within SNV through years of practice and experience. SNV developed a “Gender Self-Assessment Tool”(GSA) to monitor its performances in mainstreaming gender. The Gender Self-Assessment Tool is a methodology for SNV programmes that focuses on improving the organisation’s performance with respect to gender equity and women’s empowerment. “Mainstreaming Gender into SNV’s Corporate Standards: a Preliminary Guide”, was a first initiative to capitalise on SNV knowledge and experience in mainstreaming gender in advisory services. This guide seeks to deepen this capitalisation in the area and focuses specifically on gender mainstreaming in value chain development.
