The Worlddidac Quality Charter is a quality certification for companies who participate in educational projects worldwide. The certification goes beyond existing ISO standards by providing the assurance that a company has the capacity to deliver products and services that contribute to quality education and sustainable results. WQC-certified companies have demonstrated their commitment to education and the standards of best practice for product quality, after sales support, corporate governance, educational excellence, innovation and long term stability. The Worlddidac Association has served learning and teaching since 1952.
