Another Yardstick: HKU’s Ten-Year Trajectory in the THE World University Rankings

Another Yardstick: HKU’s Ten-Year Trajectory in the THE World University Rankings

In a nutshell: The University of Hong Kong (HKU) ranked 33rd globally in the Times Higher Education (THE) World University Rankings 2026 edition^※ (released October 2025, the highest in Hong Kong, up two places from 35th the previous year). It scored 96.6 in the International Outlook pillar—among the top three locally^※—and 95.6 in Research Quality, yet Teaching (68.3) and Research Environment (70.8) dragged down the overall score. This “five-pillar, 18-indicator” yardstick is utterly unlike the QS rankings; it sketches a different portrait of HKU altogether.

Data compiled: June 2026 (yearly ranks refer to the ranking edition years noted below).

# What Is THE, and How Is It Fundamentally Different from QS?

The answer: The Times Higher Education World University Rankings are published by the UK-based magazine. The 2026 edition assessed 2,191 universities from 115 countries and regions^※, synthesising a total score from five pillars and 18 indicators: Teaching Environment, Research Environment, Research Quality, International Outlook, and Industry. The heaviest single indicator is Research Reputation (18%), and bibliometric data is sourced from Elsevier’s Scopus database. This overlaps with yet is essentially different from the QS approach, which relies on an academic reputation survey (30%), QS’s own proprietary survey, and also uses Scopus.

The ranking gap between HKU’s positions in these two league tables is revealing: THE 2026 places HKU at 33rd, QS 2027 at 11th—a difference of roughly 22 places. The root cause is that QS assigns an extremely high weight to nearly half its indicators—reputation accounts for 45%—and combines this with internationalisation, whereas THE independently measures both the volume of research output and research reputation, and devotes almost 30% of its weight to “Teaching Environment” alone. HKU’s strengths—international faculty, international students, and international co-authorship networks—score highly on both lists. But THE’s teaching indicators examine detailed criteria such as student-to-staff ratio, the ratio of doctoral to bachelor’s degrees awarded, and institutional income, which make the differences between comprehensive research universities and more specialised institutions more visible.

# What Do THE’s Five Pillars Actually Measure, and What Changed in the 2024 Edition?

The answer: In the 2024 edition (the 20th iteration), THE undertook its largest methodological overhaul since the rankings began^※. The former “Citations” pillar was renamed “Research Quality” and split from a single indicator into four separate ones. Simultaneously, “Industry Income” was renamed “Industry” and a new patents-citation indicator was added. This redesign directly affects how all universities compare over time; understanding it is a prerequisite for reading HKU’s trajectory correctly.

The following table sets out the weightings and sub-indicators for the five pillars in the current 2025/2026 edition:

Three key changes in the 2024 edition: First, “Research Quality” was broken from a single metric into four dimensions, allowing the proportion of highly cited papers and cross-disciplinary impact to be scored independently—generally a boon for Hong Kong institutions with deep research expertise. Second, the “Industry” pillar gained a patents-cited indicator. Third, the reputation survey polled over 35,000 respondents, up from roughly 10,000^※, with a cap of 10% on self-voting from any single institution, lending the results greater representativeness.

# What Is HKU’s Ten-Year Ranking Trajectory in THE?

The answer: HKU’s ten-year trajectory in the THE World University Rankings can be divided into four phases: “early fluctuation—mid-period surge—later volatility—recent stabilisation and ascent.” From 2016 to 2019, it rose from 43rd to 36th; in 2020 it slipped back to 35th and bottomed out at 39th in 2021; it rebounded strongly in 2022–2023, reaching its all-time-high zone of 30th–31st; it fell back to 35th in 2024–2025; and resumed its upward climb to 33rd in 2026.

Three observations can be drawn from this curve. First, external shocks can temporarily depress reputation survey scores: the drop to 39th in the 2021 edition was directly linked to a decline in the density of cross-border academic exchanges following the social events of 2020. Second, the methodological overhaul in the 2024 edition hit HKU far less than it did the QS ranking: THE rank dropped from 31st to 35th (a fall of 4 places), whereas in the same year QS dropped HKU from 21st to 26th. Third, 30th place in 2022 marks HKU’s historical peak in THE to date, reflecting the concentrated impact of a pandemic-era accumulation effect from a growing number of Clarivate Highly Cited Researchers and Scopus publications.

# The Five Pillar Scores in the 2026 Edition: Where Is HKU Strong, and Where Is There Room to Grow?

The answer: In the THE 2026 edition, HKU achieved an overall score of 80.5 and ranked 33rd globally^※. Among its five pillar scores, International Outlook (96.6), Industry (96.5), and Research Quality (95.6) are all near-perfect, whereas Teaching Environment (68.3) and Research Environment (70.8) sit in a middling range. The direct reason for the lower scores in these two pillars is that, as defined by THE, “teaching reputation” and “research reputation” carry slightly less weight in the minds of global scholars compared with higher-ranked institutions such as Oxford, MIT, and Cambridge.

This table explains why HKU’s THE rank (33rd) is far lower than its QS rank (11th). “International Outlook” carries only a 7.5% weighting in THE, whereas in QS, the combined weighting of international faculty, students, and research network is roughly 15%. Meanwhile, THE assigns nearly 60% of its total weight to “Teaching Environment + Research Environment”, and within each of these, nearly half of the score comes from the reputation survey. HKU’s teaching and research reputations are certainly in the global top 30–40 range, but a cumulative gap exists in reputation surveys compared with institutions perennially lodged in the top five, such as Oxford, MIT, and Harvard. This structural gap will not close in a year or two, but given the rapid recent increase in Highly Cited Researchers—HKU had 54 Clarivate Highly Cited Researchers in 2025^※—sustained accumulation in research quality will eventually push the reputation scores upwards.

# THE’s “World’s Most International Universities”: Where Does HKU Rank on This Yardstick?

The answer: In the THE specialist ranking, the World’s Most International Universities 2026, HKU places 3rd globally. The top two spots are also taken by Hong Kong institutions—City University of Hong Kong in 1st place (for the third consecutive year), and The Hong Kong University of Science and Technology in 2nd^※. This independent amplification of THE’s International Outlook pillar assesses the proportion of international students, international staff, international co-authored papers, and an international reputation survey.

This ranking corroborates the analysis in the previous section: HKU is near its ceiling on “international outlook.” The main room for improvement lies in the two other, heavier pillars—“Teaching Environment” and “Research Environment.” The core driver of the latter is the academic reputation survey (accounting for roughly 33% of the total weighting), a slow-moving variable that rises only gradually in the short term, nourished by the publication of a large volume of high-impact papers and growth in the number of highly cited researchers.

# THE vs. QS: Why Are the Two Rankings for the Same HKU So Far Apart?

The answer: The THE 2026 edition places HKU at 33rd, while QS 2027 puts it at 11th—a gap of over 20 places. The root cause lies in entirely different weighting priorities. QS assigns nearly half its weighting (45%) to reputation surveys (academic + employer) and also factors in internationalisation and student-to-staff ratio. THE sets Research Quality (30%) and Teaching Environment (29.5%) side by side as its heaviest pillars, while International Outlook accounts for only 7.5%. HKU is near the ceiling on internationalisation, so QS gives it a stronger boost. THE’s teaching and research reputation indicators together account for 33% of the total weighting—a slow variable that HKU must keep accumulating. The two ranks point to different things and are not contradictory. For a detailed methodological comparison, see QS & U.S. News: A Five-Year Deep Dive.

# HKU in THE Subject Rankings: Which Disciplines Shine Brightest Under This Yardstick?

The answer: In the THE World University Rankings by Subject 2026, HKU ranks 1st in Hong Kong in 9 out of 11 subject areas^※. Education Studies, at 7th globally, is the flagship discipline. Medical & Health at 18th globally, Law at 27th, and Social Sciences at 33rd form another cluster of core strengths.

THE subject rankings calculate “Research Quality” using a subject-normalised method. Disciplines with a high density of international co-authorship and strong citation impact—such as medicine and law—therefore stand out prominently. Education Studies ranking 7th in THE and 1st globally for three consecutive years in U.S. News form a resonance: the more a yardstick relies on pure bibliometrics, the better these high-impact-paper disciplines perform.

# How to Explain HKU’s THE Trajectory to Anyone in One Sentence?

The University of Hong Kong’s ten-year trajectory in the Times Higher Education World University Rankings can be summarised as a single arc: from 43rd in the 2017 edition to 36th in 2019, and up to its all-time high of 30th in the 2022 edition^※, it weathered two brief bouts of volatility—the pandemic-hit 2021 edition and the methodology overhaul of the 2024 edition—before rebounding to 33rd in the 2026 edition^※. This yardstick tells us that HKU’s internationalisation and research quality are already nearing the global top tier (96.6 for International Outlook, 95.6 for Research Quality^※). The key to pushing the university’s overall rank from the 30s into the 20s lies in the steady accumulation of research reputation and teaching reputation—two slow-moving variables driven by a long-term international academic presence. And HKU is advancing steadily towards that goal, via the rapid growth of its Highly Cited Researchers and its sustained strategy of international talent recruitment.
