Roland Peter Wright, 83, of Crown Lane, Farnham Royal, was found guilty of abusing five boys aged between eight and 13 by an Amersham Crown Court jury.
He had denied 10 charges of indecent assault and two of indecency with a child at Caldicott Preparatory School.
Wright, who was headmaster for 25 years until his retirement in 1993, committed the offences between 1959 and 1970. He had been cleared of three other charges at an earlier trial.
Det Sgt Joe Banfield, of Thames Valley Police, said: “This result would not have occurred without the support of the many victims and witnesses in this case, who bravely gave evidence and provided statements.”
Ruth Bowskill, of Thames and Chiltern Crown Prosecution Service, paid tribute to the victims of those found guilty of abuse for their “strength and tenacity in coming forward and giving evidence”.
Wright’s conviction, on Tuesday, comes after fellow former teachers John Addrison and Hugh Henry pleaded guilty to sex abuse, it can now be reported.
