The ONCE Foundation for Cooperation and Social Inclusion of People with Disabilities was created in February 1988, by agreement of the ONCE General Council, and was presented to society in September of that same year as an instrument of cooperation and solidarity of Spanish blind individuals toward other groups of people with disabilities for the improvement of their living conditions. In addition to ONCE itself, as a founding entity, the main organizations of people with disabilities in Spain are present in the ONCE Foundation, through its Board of Trustees, its highest governing body. It also includes the Spanish Committee of Representatives of People with Disabilities (CERMI), which brings together the main organizations of people with disabilities, representing the 3.8 million people with disabilities and their families in Spain.
ONCE Foundation's main source of funding for each year comes from 3% of the gross income obtained from the marketing of ONCE's games of chance. This figure represents one euro out of every three that ONCE devotes to social services.
