Farm Field School's farmer training has positively impacted farmers to access new knowledge in agricultural production. At the same time, FFS is also a model to strengthen farmers' critical production practices. The results of the FFS study in Vietnam have shown positive effects, from improving knowledge levels to applying techniques to field production. For the FFS used in Vietnam, specific principles and features such as classes conducted at farmers' residences and technical tests are always designed in the course. From the FFS course, farmers have been able to access new science and technology, acquire new knowledge, and, more importantly, be empowered in production activities in the field.
