This report is a record of the results of the research project “Promoting community learning to develop OTOP product to the five-star level: a case study of Bang Jaocha woven bamboo products groups in Pothong District, Ang Thong Province.” It is concerned with the development of products for the “One Tambol, One Product” or OTOP policy; a policy that was designed to promote the grassroots economy and local development. Under OTOP, people in communities were encouraged to participate in the development, production and sale of new products using their own local raw materials, intellect and resources. It is a way to promote self sufficiency by developing the grassroots economy. To evaluate OTOP products and promote high standards, government agencies set up system of judging products on a tambol, district and provincial level and awarded them a rating of one to five stars. However, in practice it seems that the development of five-star level OTOP products was mainly driven by the government sector. Government agencies sent officials to advise and/or train people in the communities so that they could produce high-quality products, but the people did not fully participate in the complete product development process. There was a lack of mechanisms to promote efficient public participation in the process. The purpose of this research project was to build up a community learning process for five-star OTOP product development that is truly participatory and sustainable, based on a pilot project with five woven bamboo products groups in Bang Jaocha Tambol, Pothong District, Ang Thong Province.
