It is situated approximately three miles (5 km) west of Saltash, in the civil parish of Landrake with St Erney (where the population of the 2011 census was included.).

The school takes its name from Landrake-born Sir Robert Geffery who, in 1704, bequeathed money to set up a trust to educate children of the parish.

[6] King Edmund gave the parish of Landerch to Bishop Burhwold in exchange for land in Devon;[7] in 1018 this gift was confirmed by King Cnut who declared the gift had really been for the benefit of the monastery of St Germans where the bishop had his see.

The gift included the parish of Landrake with its chapel of St Erney; these continued to be held by the monastery after the see was moved to Devon.
