Doctorates are issued with various designations, depending on the faculty: e.g., Doktor der Naturwissenschaften (Doctor of Natural Science); Doktor der Rechtswissenschaften (Doctor of Law); Doktor der Medizin (Doctor of Medicine); Doktor der Philosophie (Doctor of Philosophy), to name just a few. Multiple doctorates and honorary doctorates are often listed and even used in forms of address in German-speaking countries. A Diplom, Magister, Master's or Staatsexamen student can proceed to a doctorate. Well qualified bachelor's graduates can also enrol directly into PhD programs after a procedure to determine their aptitude administered by the admitting university. The doctoral degree (e.g., Dr. rer. nat., Dr. phil. and others) is the highest academic degree in Germany and generally a research degree. The degree "Dr. med." for medical doctors has to be viewed differently; medical students usually write their doctoral theses right after they have completed studies, without any previous conducted scientific research, just as students in other disciplines write a "Diplom", "Magister" or "Master's" thesis. Higher doctorates, such as the D.Sc. degree in the UK, are not present in the German system.
