Worth School will have a new head master from September 2015 after the current head announced his retirement.
The Abbot of Worth and the chairman of governors at the school said Stuart McPherson would take over from Gino Carminati, who has served the school for eight years.
Mr McPherson is currently house master of Penn House at Eton College and teaches English.
A spokesman for Worth School, in Turners Hill, described how the new head’s career had taken him all over the world.
He took his Bachelor’s degree at the University of Western Australia before completing an MA in Literature and Religion at Newcastle University.
Mr McPherson taught at Sydney Grammar School from 1990-2000 and has been at Eton since 2000.
He is married to Johneen, who is the director of studies at St Mary’s School, Ascot, and they have four children aged between 14 and 21.
Mr McPherson will be the seventh head master of Worth School, and the third lay head master in the school’s 55-year history.
