This they did in 1912, developing the two schools which ceased to be fee paying, into Central Schools on a site in Stewart's Grove, Chelsea. During both World Wars, sixty six Oratorians lost their lives fighting for their country, with some of the men having been members of the Oratory Cadet Corps. The vast majority of Oratory boys joined the Army or RAF, but a select few did join the Royal Navy. Old Oratorians were recipients of decorations, such as the Croix de Guerre, the Distinguished Conduct Medal and the Military Cross. On the outbreak of war in 1939, the school, together with Fr Dale-Roberts of the Oratory, moved to Tonypandy in South Wales, whilst the school site in Stewart Grove was taken over by the War Office and used as a high status internment camp. In 1959 the two central schools were amalgamated and in 1962 it was decided that the Daughters of the Cross were to be withdrawn after almost a century of devoted work. In 1963 the school was classified as a four-form entry grammar school admitting only boys since there were already many more selective places for girls than boys in the schools in the diocese. However those girls currently at the school were, on the insistence of the newly appointed headmaster (who had applied for and been appointed head of a mixed school), allowed to remain at the school to complete their education. The school moved to its present site in 1970, now with six forms of entry (180) at 11+, with girls being admitted annually to the sixth form. In September 1989 the school, formerly a voluntary-aided school, became a grant-maintained school, continuing in the trusteeship of the Fathers of the London Oratory, who own the building and grounds and appoint the majority of the governors. The Junior House, occupying a newly built block adjacent to the Arts Centre, was opened in September 1996, to which 20 seven-year-old boys are admitted for a specialist music education, with a strong emphasis on Catholic liturgical music. Under the Academies Act 2010, the school became an Academy in August 2011. The school marked its 150th anniversary on 27 September 2013 with the celebration of Mass in Westminster Cathedral.
