Numerus clausus ("closed number" in Latin) is one of many methods used to limit the number of students who may study at a university. In many cases, the goal of the numerus clausus is simply to limit the number of students to the maximum feasible in some particularly sought-after areas of studies. However, in some cases, numerus clausus policies were religious or racial quotas, both in intent and function.
The numerus clausus is used in countries and universities where the number of applicants greatly exceeds the number of available places for students. This is the case in many countries of continental Europe.
Students in much of Europe choose their field of specialization when they begin university study, unlike students in North America, who specialize later. Fields such as medicine, law, biology, dentistry, pharmacology, psychology and business administration are particularly popular and therefore harder to gain admittance to study.
In France, admission to the grandes écoles is obtained by competitive exams with a fixed, limited number of positions each year. Also, at the end of the first year of medical studies in universities, there is a competitive exam with a numerus clausus for determining which students are allowed to proceed to the second year; in later years of medical studies there is a competitive exam (concours de l'internat) for choosing medical specialties.
In November 2002 the Brazilian government passed Federal Law 10.558/2002, known as the "Quota Law". The law allowed for the establishment of racial quotas at public universities. In 2012 the Supreme court of Brazil unanimously upheld the law.
The numerus clausus is used in Germany to address overcrowding at universities. There are local admission restrictions, which are set up for a particular degree program (Studiengang) at the university's discretion, and nationwide admission restrictions in medicine, dentistry, veterinary medicine, and pharmacy. Not all degree programs restrict admissions. The most common admission criterion is the final grade of the university entrance qualification, that is the school leaving certificate formally allowing the applicant to study at a German university. Typically, this is the Abitur. The final grade takes into account the grades of the final exams as well as the course grades. In colloquial usage, numerus clausus may also refer to the lowest admitted grade in this process. Other criteria, e.g. interviews, are increasingly common as well.
