German Universities in the Times Higher Education (THE) World University Rankings

Times Higher Education (THE), formerly the Times Higher Education Supplement (THES), is a London‑based magazine that focuses on higher education–related news, analysis and data.

Since 2004, THE has been known for publishing annual global university rankings, initially in collaboration with Quacquarelli Symonds (QS) before each organisation went on to develop its own ranking system. Over time, THE has worked with different data partners (first QS, then Thomson Reuters, and now Elsevier, whose Scopus database underpins the bibliometric indicators) and has continuously refined its ranking methodology in consultation with universities, readers and its editorial advisory bodies. In the early years, the World University Rankings covered around 400 institutions; since then, the rankings have expanded steadily and now include about 2,000 research‑intensive universities worldwide.

Keep in mind: just like any other ranking, THE Rankings have limitations that students should be aware of (see “Criticism” section).

Criticism of university rankings tends to revolve around a handful of recurring themes, and the THE ranking is no exception. Here are some of the most commonly discussed concerns:

• Reliance on reputation surveys — a significant share of the overall score (33%) is derived from academics' perceptions of which universities are "the best." Critics argue that this measures brand recognition and prestige rather than actual performance, and that it creates a self-reinforcing cycle: well-known institutions attract more votes, which keeps them at the top, which keeps them well-known. Some institutions (e.g., from India) even boycotted participation in the ranking due to excessive emphasis on perception (and thus prestige) (see, e.g., The Times of India).
  
  It is noteworthy that THE has responded to wider concerns about survey integrity by introducing a self-voting cap (limiting self-votes to 10% of a university's total) and monitoring unusual voting patterns between institutions.
   
• Language and disciplinary bias — the ranking draws its bibliometric data from Scopus, which predominantly indexes English-language journals. This can disadvantage universities that publish mainly in other languages or that focus on disciplines like the humanities and social sciences, where impactful work often takes forms other than peer-reviewed journal articles (such as books, exhibitions, or policy reports). 
  
  While THE has adjusted citation weightings for some subject rankings (for example, halving the citation weight for arts and humanities), critics maintain that the system still structurally favours English-language, STEM-oriented research cultures. A United Nations University expert group raised this concern in 2023, noting that major ranking methodologies — including THE's — show a bias towards the English language and STEM subjects, which undermines recognition of teaching and the humanities.
   
• Citations as a dominant but vulnerable metric — the Research quality pillar, which accounts for 30% of the total score, is built entirely on citation-based indicators. While citations are a widely accepted measure of research impact, they can be distorted in several ways. The academic community has raised growing concerns about citation manipulation practices such as mutual citation rings and paper mills, which can artificially inflate an institution's scores. 
  
  Citations are also susceptible to event-driven spikes: for instance, during Covid-19 times, several institutions rose sharply just because they had published heavily on Covid-19. Because THE uses a five-year publication window, such effects can linger in the rankings long after the underlying cause has passed. While the introduction of new metrics like Research strength, Research excellence and Research influence in 2023 has diversified how citations are measured, the fundamental reliance on citation volume remains a point of debate.
   
• Advantage for wealthy institutions — because several indicators (institutional income, research income, industry income) are directly tied to financial resources, the ranking tends to reward universities that are already well-funded. This has led to criticism that it reinforces existing hierarchies rather than recognising quality teaching or research on a level playing field, particularly for institutions in lower-income countries that may deliver excellent education with far fewer resources (see e.g., Research Gate).
   
• Rankings as an artificial zero-sum game — some scholars question the very logic of ranking universities on a single scale. The argument is that reputation is not a scarce resource in the way rankings imply — one university can improve without another necessarily declining. By forcing a strict hierarchy, rankings may distort how we think about quality in higher education and push institutions toward chasing metrics rather than pursuing their distinct educational missions (see e.g., LSE Impact Blog).
   
• Expanding pool dilutes positions — as the total number of ranked institutions has grown over the years, many universities have seen their numerical rank drop simply because more competitors entered the table. Critics point out that a declining rank may not indicate declining quality at all, but rather an expanding denominator — a nuance that often gets lost in headlines and institutional strategy discussions.
