The roles of community training centers (CTCs) in community development and housing provision in developing countries from the perspective of assisted self-help housing. It reviews a Korean community center that contributed to community-led self-help housing for low-income groups in the 1970s. It also reviews a few notable community training centers (CTCs)s from India, Uganda, Nepal, and three countries in Central America to examine the functions and contributions of the community training centers (CTCs). It was found that community training centers (CTCs) play a central role in community empowerment and the production of affordable building materials receiving technical or financial assistance from non-governmental organizations (NGOs) and governments. The paper makes a compelling case for community training centers (CTCs) by drawing on these exemplary cases to provide a development model that has the potential to facilitate the improvement of the living environment in developing countries.
