Many university staff members serve on the boards of international professional and scientific associations or are invited to act as advisers by the WHO and IAEA. Lekarsz and Doktor (stopień naukowy) degrees awarded at the university enjoy wide national recognition. In some countries, e.g. Germany, they are accepted with no further confirmation requirements. They are routinely accepted in Sweden, Britain, the United States and Canada. At present more than 1200 graduates of the university practice or research abroad. Many of them are clinical specialists and heads of hospital departments in Europe, North America, South Africa and elsewhere.
