In February 1912 he gave up his position as Chief Registrar to become Secretary (and then legal adviser) to the English Insurance Commission, with the newspapers of the time reporting that he had had "three promotions in two months", a consequence of his high standing with Morant. During this period he was also involved in drafting education bills with Arthur Thring. The commission was "a galaxy of future Whitehall stars", and contained many individuals who would later become noted civil servants in their own right, including Morant, Schuster, John Anderson, Warren Fisher and John Bradbury. The contacts Schuster made during his time on the committee were instrumental in advancing his career; as a lawyer rather than a dedicated civil servant he was considered an outsider, and the links he made – particularly the friendships he struck up with Fisher and Anderson – helped allay this to some extent.
