University Study-Oriented System (called USOS) is a student management information system used in almost 100 Polish universities, technical universities, higher vocational institutions, university schools of physical education and other types of high education institutions. Among these schools are top public universities in Poland, like the University of Warsaw, Jagiellonian University from Kraków, Adam Mickiewicz University from Poznań, and Nicolaus Copernicus University from Toruń.

From the functional point of view USOS is probably a typical software information system supporting management of higher education at university level. What makes it unique is the, unification of services at country level and integration achieved from effective cooperation of universities who jointly develop and deploy the system on a scale hardly to be found not only in Poland, but also other European countries. It is the only system of that kind in Poland, being built by universities for universities, with a business model acceptable to even the smallest institutions.
