QUANGO: 'Quasi-autonomous NGO,' such as the (ISO). (The ISO is actually not purely an NGO, since its membership is by nation, and each nation is represented by what the ISO Council determines to be the 'most broadly representative' standardization body of a nation. That body might itself be a nongovernmental organization; for example, the United States is represented in ISO by the American National Standards Institute, which is independent of the federal government. However, other countries can be represented by national governmental agencies; this is the trend in Europe.)
National NGO: A non-governmental organization that exists only in one country. This term is rare due to the globalization of non-governmental organizations, which causes an NGO to exist in more than one country.
PANGO: 'Party NGO,' set up by parties and disguised as NGOs to serve their political matters.
SNGO: 'Southern NGO'
SCO: 'Social Change organization'
TNGO: 'Transnational NGO.' The term emerged during the 1970s due to the increase of environmental and economic issues in the global community. TNGO includes non-governmental organizations that are not confined to only one country, but exist in two or more countries.
