Universities fall into two categories: universities created by the private sector after 1980 and which are known as private universities, and universities which are members of the Consejo de Rectores de las Universidades Chilenas, or CRUCH, and are known as traditional universities. CRUCH universities include 16 state, 6 Catholic and 3 private lay universities. Students in these have access to a range of subsidised financing, while students in non CRUCH higher education institutions have far fewer (and largely unsubsidised) options. CRUCH universities receive both a direct subsidy from the State in the form of a block grant (Aporte Fiscal Directo, AFD), and part of an indirect grant (Aporte Fiscal Indirecto, AFI) that is allocated to institutions that attract the 27 000 students with the top PSU scores. Private universities, on the other hand, finance themselves largely through student tuition and the AFI.
