Our seal of quality is an internal quality certification for our member schools. We check the quality of the schools’ facilities, administration, human resources, teaching standards, cultural programme, services, customer care and transparency in promotional activities. We encourage the schools to engage with their community and with cultural initiatives and environmental organisations. This takes the form of donations, buying from non-profit organisations, actively supporting campaigns and projects, and choosing fair-trade products. TANDEM schools support sustainable, environmentally and socially responsible tourism.
