Europe's Doctorate Label Turned 35 This Year. Almost Nobody Awards It.
The Doctor Europaeus was supposed to set a continent-wide standard for PhD quality — but a quarter-century on, fewer than twenty universities have signed on, and nobody can tell you which ones they are.

A Gold Standard Nobody Tracks
In 1991, the liaison committee of the European Union rectors' conferences introduced a supplementary certificate called the Doctor Europaeus. Universities would award it themselves, on their own authority, to doctoral graduates who met four straightforward conditions: a research stay of at least three months in another European country, a thesis reviewed by at least two scholars based in two different European nations, at least one examiner from abroad on the defence panel, and a portion of the defence conducted in a European language other than that of the awarding institution. Thirty-five years later, Uwe Brandenburg, managing director of the Global Impact Institute, set out to find which universities actually grant it. His repeated searches turned up roughly eighteen, scattered across no more than five countries and heavily concentrated in Italy and France. Among them: Ferrara, Udine, Trieste, Cagliari, Naples, Sapienza in Rome, and Urbino on the Italian side; Paris-Saclay, Grenoble Alpes, Orléans, and Aix-Marseille in France; Cologne in Germany; and Coventry in the United Kingdom. Spain, once an early adopter, formally swapped its "European Doctorate" mention for an "International" one in 2011.
The Four Conditions That Were Supposed to Be Normal
The Doctor Europaeus was a certificate attached to existing national doctorates, not a new degree — a lightweight mechanism for recognising international work without creating new legal frameworks. Instituted in 1991 by rectors' conferences, it required candidates to spend at least three months researching abroad, have their thesis evaluated by reviewers in multiple European countries, include a foreign examiner on the defence panel, and defend in a language other than their home country's. The four conditions were called a gold standard. More than three decades on, they have not become standard practice. Evaluation work consistently shows that for most doctoral candidates — often the majority — these international elements remain the exception, regardless of whether the label exists at their institution.
Why the Label Stalled
Several structural factors explain the low uptake. The label carries no legal force and no supranational oversight; a university adopts it voluntarily and verifies compliance internally. That lightness was meant to be a feature, not a bug, but it also meant no institution was accountable for promotion or expansion. There is no central, searchable register — no directory telling a prospective doctoral student which European universities offer the label, under what criteria, or in which disciplines. The European University Association, which brings together Europe's doctoral schools and defines the standards the label rests on, has never hosted such a record. Meanwhile, the landscape the label was designed for has shifted dramatically. The Salzburg Principles, whose twentieth anniversary the EUA marked in 2025, reshaped how Europe structures the PhD. Open science, FAIR research-data management, transferable skills, and reformed research assessment have all moved from aspiration to policy. Sixty-four European Universities alliances now connect more than 560 institutions, many delivering joint doctoral training. The European Commission's 2024 blueprint for a European Degree Label is already in pilot phases. Against that backdrop, a certificate whose criteria were frozen in 1991 looks less like a standard and more like an artefact.
Doctor Europaeus+: A Modernisation Proposal
Brandenburg has put forward a revised version he calls Doctor Europaeus+, keeping the original four conditions as a floor and layering on indicators aligned with current European doctoral policy. The additions would require doctoral training consistent with the EUA Council for Doctoral Education's principles, documented instruction in open science and research integrity, evidence of genuine international collaboration and transferable-skill development, participation in a European University alliance or comparable network where relevant, and research data management following FAIR principles. An optional portable digital badge could record these components in a verifiable format. Crucially, the proposal does not invent a new degree or demand new legal architecture. A university would adopt an internal regulation establishing the label, fold the criteria into its existing doctoral rules, set up a verification procedure, and issue the certificate once all conditions are met. Nothing requires ratification by any supranational body. Brandenburg distinguishes the label from a cotutelle — a binding bilateral agreement between two universities producing a single thesis and two diplomas, negotiated case by case — and from the European Degree Label, an EU-level instrument still taking shape through pilot projects. Doctor Europaeus+ sits below both in weight: a certificate a single institution attaches to its own national doctorate.
The Case for a Public Register
The absence of a public register is, in Brandenburg's assessment, a genuine loss for students. A candidate who wants to pursue an international doctorate in Europe has no way to search which universities award the Doctor Europaeus, in which fields, or under what criteria. A label that is adopted unevenly across a handful of countries and is not even counted by the sector that owns it cannot live up to its continental name. The fix is modest: a simple directory, hosted by the EUA, indicating which universities award the label, what criteria they apply, and in which disciplines. The EUA already represents the doctoral-school community and defines the standards the label draws on. Brandenburg argues that Europe does not need to invent a new mark of doctoral quality — it has had one for thirty-five years. What it needs is to modernise that mark into a Doctor Europaeus+, to hold institutions to it, and to record, at last, where it can be found.

PhD Training Teaches Research, Not the Rules of an Academic Career
Giovanni Straffelini, coordinator of a doctoral school at the University of Trento, argues that structured workshops on the hidden curriculum could close the gap between individual mentoring and the international reality of academic work.
