A building with a single classroom, two rooms for the Master and Usher, and a dormitory for boarders was erected in 1569 close to St Mary's Church and adjacent to the almshouses (all can still be seen today).

In 1575, the Statutes were published which not only laid out how the school should be run but established the connection with New College, Oxford that lasts to this day.

A note on one copy of the Statutes states: "On the Day before the feast of St Andrews [November 29] 1570, Edward Harris who had previously been elected master, took up his office of teaching in the newly completed school."

However, by the middle of the 19 century, its fortunes had declined and, in 1872, it was decided to temporarily close the school and make a fresh start on a site on the Oxford Road, Thame.

The Committee also accepted the Governor’s recommendation that to preserve the essential characteristic of the school, the size of the Boarding House be increased to 90.

Currently, the school is still dual-site and the long awaited plans to have a single site on the Oxford Road have yet to be reached.

However, in February 2008, a 23-year-old man called Craig Ford[7] was found guilty of arson and sentenced to five years in prison.
