This article reconstructs the educational policies of the Latin American Confederation of Christian Trade Unions (CLASC)—the name of which was later changed to the Latin American Central of Workers (CLAT) —in the context of the Latin American Cold War. It provides an empirical description of its pedagogical praxis, showing how it was shaped in constant dialogue with the region's conflictive context. It explores how they viewed political training in relation to both their organizing efforts and struggles, applying a conception that brought together “action, organization and training” as integrated elements, in the run to foster class awareness, build up a “new society,” and “workers’ organized power”.
