Gender mainstreaming to promote gender equality and include persons with disabilities is important because it can bring a huge impact to the organization and the country. It is not easy to accomplish gender equality as long as there are barriers against women's participation in all spheres. As a result, achieving gender equality is a challenge for not only developed countries but also developing countries. This thesis evaluates the implementation of gender mainstreaming to promote gender equality and the inclusion of persons with disabilities of the Division for the Advancement of Women in Lao PDR. This thesis discovers the perception of gender equality, the barriers that prevent women from achieving gender equality, and the impact of gender equality and lastly examines whether the inclusive approach to include persons with disabilities is implemented in the ministerial organization.
