Newington ceased its connection to theological training in 1914, when the Wesleyan Theological Institution moved to the newly founded Leigh College at Strathfield South. In 1921, a stone war memorial, designed by Old Newingtonian William Hardy Wilson, was opened in memory of those old boys who had paid the supreme sacrifice in World War I. A separate preparatory school was opened in 1921, after a bequest by Sir Samuel McCaughey. It became known as Wyvern House in 1938, when a new building was opened by Old Newingtonian Sir Percival Halse Rogers.
