TAGCODEC, formerly known as the Tagalog Cooperative Training and Education Center (TAGCOTEC) was born in response to a felt-need, at a time when cooperatives in Luzon were dying as fast as they were born; when enthusiasm for cooperation was so pervading, yet education and training were nowhere to be found. It was organized by a handful of cooperative leaders in Metro Manila and in various provinces of southern Tagalog and Central Luzon on July 19, 1975 at the Jesuit Sacred Heart of Novitiate in Novaliches, Quezon City. It was registered with the Securities and Exchange Commission on February 2, 1976. Moved by the ardent desire of its members to engage in economic activities in order to uplift their socio-economic condition.
TAGCOTEC re-registered with the Bureau of Agricultural Cooperatives Development (BACOD) on November 9, 1987 with a new name TAGALOG COOPERATIVE DEVELOPMENT CENTER (TAGCODEC). It has then become a regional secondary federation operating in National Capital Region (NCR), Regions 3 and Region 4. It was duly registered with CDA on May 08, 1991 with Certificate of Registration No. MLA-C669, and was re-registered with Cooperative Development Authority on November 16, 2009 with Reg. No. 9520-04002268.
