In December 1923 Galerkin was elected dean of the Polytechnical Institutes civil engineering faculty. It happened during a very important period of the institute's history, when a group of deans resigned from their posts, protesting from unceremonious intervention of so-called "student' representatives", controlled by the trade-unions and the Communist party committees, into the educational process. Galerkin showed to be a talented leader of the faculty. He managed to neutralize too active "assistants", who were appointed against his will, and he did not hurry to fulfill the orders of incompetent leaders, who were conducting infinite experiments in the higher school at that time. In 1924 - 1929 Galerkin was also a professor in the Railway Engineers Institute and in the St. Petersburg University. In 1924 he made his last trip abroad – he participated in the Congress on applied mechanics in the Netherlands.
