The main steps during your PhD process are summarized in the following overview. Please notice that it's only a working aid, only the text of the Promotion Regulationin German is legally binding.

  • Step 1: Admission as Doctoral Researcher, Matriculation

    The most important preconditions are a work theme and an academic supervisor. You should catch up on possible themes on the Institute Pages or the pages of Graduate Advancement and directly talk to professors if necessary.

    Candidates who wish to submit their thesis and to apply for conferment of the doctoral degree must have been admitted as doctoral researchers for at least three months before submission of the dissertation.

    Here you can find a summary of the necessary documents and formulars:

  • Step 2: Submission of the Thesis and Application of the Doctorate

    If all preconditions are fulfilled, the faculty will begin the examination of your thesis upon submission. Concurrently, referees and examiners as well as the chairmanship of the examining board are determined.

    Your supervisor should suggest the referees, the examining board and also suggest possible dates and rooms for your examination.

  • Step 3: Display of the Dissertation and the Reports

    In general the reports should be available six weeks after the application of disclosure. The dissertation and the reports will be displayed last at least two weeks, normally during lecture periods. The dissertation is deemed to have been accepted if all experts have recommended their acceptance and if no objection has been made against the acceptance of the work within the period of the display period.

    The thesis may be accepted conditionally. In that case, the chairperson of examiners will contact the candidate and inform him or her about necessary changes.

  • Step 4: Determination of an Examination- or Disputationdate

    After the acceptation of your dissertation, the dean decides on a date and place for the examination or the disputation and announces this information. There have to be at least five business days in between the announcement and the examination/ disputation.

    The time between the handing in of your dissertation and the earliest possible examination/disputation date is about eight weeks, depending on the arrival of the reports. The display of the reports as well as the examination/disputation usually take place during lecture periods!

    Please note: Your preferred date of your disputation has to be arranged early with the Office for Doctoral Researchers!

  • Step 5: Examination/Disputation

    Directly after the oral doctoral examination or disputation, the chairperson informs the doctoral candidate about the results and hands out a temporary certificate on the results.

  • Step 6: Publication of the Thesis

    The publication of the approved final version of the thesis within one year after the passed oral doctoral examination or disputation is obligatory. Details on the publication of dissertations can be found on the websites of the TIB. Within two weeks after handing in, the TIB normally issues a confirmation and sends it to the faculty.

  • Step 7: Promotion

    The degree is conferred by handing over or delivery of the PhD certificate. This is possible after the publication of the dissertation and the delivery of the declaration given below. It is only afterwards that the doctoral candidate has the right to lead the doctorate Dr. rer. nat.. You receive your PhD certificate at the Office for Doctoral Researchers, if all necessary documents are available.

  • International Application of Certificates

    Ph. D. certificates are issued in German. In most cases this is sufficient for applications in the international academic sector. Occasionally, a translation or an international certified copy of the German original is necessary. In the majority of cases, such a certification is issued as a so-called "Apostille" or "Legalisation".


    At Leibniz Universität translations of certificates are provided by Sachgebiet 23. Please inform us together with your application for the admission as doctoral candidate in case you need a translation. Normally, we can hand out the translation together with your Ph. D. certificate.


    For the issue of an Apostille you need an advance certification which is issued by the University Administration, Dezernat 3. Please inform us together with your application for the admission as doctoral candidate in case you need an advance certification. Normally, we can hand it out together with your Ph. D. certificate, as well.
