External PhD: What it means and how it works.
Pursuing a PhD externally means: being accepted by the university whilst working elsewhere. For working professionals, this is the usual route, and it has its own rules, its own advantages and its own pitfalls.
With an external PhD, you are admitted to the university as a doctoral candidate but are not employed there. You conduct your research alongside your job, supervised by a professor from the faculty. The degree is the same as for an internal PhD. What differs are the funding, your connection to the university, and the fact that no one from outside will be checking on your progress.
Internal versus external: a comparison
The difference lies not in the degree or the examination procedure, but in the employment relationship and the proximity to the chair. Both factors have a greater impact than might initially seem.
How the admission process works
The formal procedure is described in every set of doctoral regulations and follows a similar pattern: you apply for admission as a doctoral candidate, submit your academic transcripts, research proposal and confirmation of supervision, and a faculty committee makes the decision. In many sets of regulations, the time limits only begin to run once you have been admitted.
In practice, everything is decided beforehand, namely when the confirmation of supervision is granted. Without it, there can be no application, and you do not obtain it via a form, but rather through academic suitability.
How supervision is arranged
Your topic must fall within the research field of the professorship, and your research proposal must demonstrate that the project is viable. The usual procedure is as follows: an outline of the topic, researching suitable departments through their publications, initial contact with a one-page brief proposal, an interview, followed by the detailed research proposal.
Anyone who sends mass emails to thirty departments will usually receive thirty rejections. Five well-prepared enquiries are more likely to succeed and take less time.
What makes it more difficult from a distance
What is sorted out informally in-house requires a scheduled meeting when dealing with external parties. Regular intervals in communication can compensate for the lack of physical proximity, but only if they actually take place.
Without an external rhythm, the work gets pushed aside by day-to-day business. Interim targets with deadlines and a fixed meeting with the supervisor counteract this.
There is a lack of interaction with other PhD students. Colloquia, conferences and specialist groups are therefore not mere extras, but an integral part of the work.
Access to literature, statistical software and computing capacity are not automatically provided externally. Clarify at an early stage what is covered by your enrolment.
What makes external study easier
The external route offers tangible advantages that are rarely found within the university: you are free to choose your topic, are not bound by project timelines, generally have access to a field that others have been vying for for years, and are independently funded.
For many research questions, access to real-world practice is the real competitive advantage. A research group specialising in your topic is well aware of this.
Our role in the external route
We prepare precisely the areas where external projects often falter: ensuring a good fit between your topic and the department, drafting a robust research proposal, establishing a realistic timetable, and making a smooth initial contact. To this end, we analyse the doctoral regulations of your target faculty so that requirements and deadlines are clear from the outset.
The faculty decides on admission; the university decides on the award of the degree. We ensure that your application does not fail due to avoidable reasons.
Frequently asked questions.
What is an external PhD?+
A PhD where you are admitted to the university but do not work there. Funding comes from your job, and the topic often stems from your professional practice.
Is an external PhD less recognised?+
No. The requirements, assessment and degree are identical. The difference lies in the path taken to achieve it, not in the result.
How do I find a supervisor for an external PhD?+
Through academic fit. Research departments that publish on your topic and approach them with a concise, one-page outline.
Can I do an external PhD at any university?+
No. Whether external candidates are accepted, and under what conditions, is governed by the respective doctoral regulations. Some faculties require additional coursework or an aptitude assessment.
Do I need a co-supervisor?+
Generally speaking, yes – at the latest by the time of the assessment. Sorting this out early on helps avoid delays towards the end of the process.
Do I have access to the library?+
Usually yes, once you’ve enrolled, including access to databases. Check the scope of access before budgeting for literature costs.
When does the deadline start?+
Under most regulations, it starts from the date of acceptance as a doctoral candidate, not from the initial idea. This determines the actual time you have available.
