The Perse School is a public school (English independent day and, in the case of the Perse, a former boarding school) in Cambridge, England. Founded in 1615 by Stephen Perse, its motto is Qui facit per alium facit per se, taken to mean 'He who does things for others does them for himself'. The School began accepting girls at 11 and 13+ in September 2010 and was fully co-educational by September 2012. 'Perse' is a member of the Headmasters' and Headmistresses' Conference, an association of the leading UK independent schools.
