Great Tower. Grant-aided status After the First World War, the school opted into the arrangements of the Education (Administrative Provisions) Act 1907, and as a grant-aided secondary school had to guarantee a quarter of its places as free scholarships for boys from public elementary schools. Of this decision, Stanier, a former Master and the author of the school history, writes: The origins of the present-day school site begin in the late 19th century, when the school was occupying part of the college grounds alongside Longwall Street. It was slowly relocated by a few hundred feet, over Magdalen Bridge, onto the present site on Cowley Place began under the tenure of W. E. Sherwood in 1891 when, after an outbreak of scarlet fever in the old boarding house on the corner of Longwall Street and the High Street (ascribed partly to the dilapidated state of the building and in particular to the drainage) plans for a new school house were laid out.

The choristers still today make this short daily journey, but using a tunnel under Magdalen Bridge to avoid crossing the busy road. The school continued to grow during the early 20th century, and by 1925, there were about 170 students. Migration to Cowley Place In 1928, increased pressure on the Magdalen College buildings on Longwall Street caused the migration of the entire school over Magdalen Bridge. Plans were made for new buildings designed by Giles Gilbert Scott, but this period was marked by uncertainty for the school, as in 1926 the College statute referring to the School had been altered. "Where before it had ordained that the College should always maintain the School, it now ran, 'So long as the grammar school of the College in Oxford is maintained....". As a result, temporary classrooms were built along Cowley Place, most of which are still standing today. The buildings that the school had used on Longwall Street underwent a change of use or were redeveloped, and now form part of the College buildings: the School's original 'Big School' became the present-day "New Library" of the college, and the former
