 This focus on sustainability has resulted in four of CFGS's feeder primaries pursuing a simultaneous programme of ESD development.Additionally, the ESD programme has seen CFGS establish links to Peruvian schools; in recent years this relationship has manifested itself in triannual trips, some as student exchanges.Various educational development projects conducted by CFGS pupils have made a worthwhile contribution to the partner pupils and in the UK, past activities have seen pupils design calendars in support of the on-going partnership.
