Global rankings mostly measure research reputation and output, not the quality of teaching you would receive. QS draws half of an institution's score from academic reputation and research citations, while Times Higher Education groups 18 indicators into five pillars of which two are research pillars. A more useful method is to confirm the institution's official status with the national quality assurance body, then compare course content, teaching approach, total cost and graduate outcomes in your specific field.
Rankings are the first thing most families look at and the least suited to the decision they are making. They are not dishonest, and the organisations that produce them publish their methods openly. The problem is that what they measure and what a student needs to know are different things, and the gap between the two is wider than most people realise.
This article explains what the tables actually contain, what official quality assurance exists instead, and what to compare once you stop comparing rank numbers.
Understanding QS, Times Higher Education and Other Rankings
The two most widely cited tables are produced by QS Quacquarelli Symonds and Times Higher Education. They are different products measuring different things, which is why the same university can sit forty places apart in the two tables in the same year. Neither is wrong. They are answering different questions.
According to QS, the overall score is built from weighted indicators, and half of an institution's position comes from what QS calls its Research and Discovery lens: academic reputation at 30 per cent and citations per faculty at 20 per cent. A further 20 per cent comes from employability and outcomes, made up of employer reputation at 15 per cent and employment outcomes at 5 per cent. Faculty to student ratio, the indicator closest to describing teaching resource, carries 10 per cent. International faculty ratio, international student ratio and international research network carry 5 per cent each.
Times Higher Education takes a different approach, grouping 18 performance indicators into five pillars: teaching as the learning environment, research environment covering volume, income and reputation, research quality covering citation impact and research strength, international outlook across staff, students and research, and industry. THE describes its tables as judging research-intensive universities across their core missions, and draws bibliometric data from Elsevier's Scopus database, using 174.9 million citations to 18.7 million publications from 2020 to 2024.
| Aspect | QS World University Rankings | THE World University Rankings |
|---|---|---|
| Structure | Indicators grouped into lenses, with published percentage weightings | 18 indicators grouped into five pillars |
| Largest component | Academic reputation, 30 per cent | Two of the five pillars are research pillars: research environment and research quality |
| Teaching measure | Faculty to student ratio, 10 per cent | A teaching pillar covering teaching reputation, student to staff ratio, doctorate ratios and institutional income |
| Employer view | Employer reputation at 15 per cent and employment outcomes at 5 per cent | An industry pillar based on industry income and patents rather than graduate employment |
| Scope | Nominations collected for approximately 7,000 institutions each year | Explicitly aimed at research-intensive universities |
Compiled from the published methodologies of QS Quacquarelli Symonds and Times Higher Education, checked on 27 July 2026. Both organisations revise their methods periodically. Current weightings are on their own methodology pages.
Other tables exist as well, including ShanghaiRanking's Academic Ranking of World Universities, the CWTS Leiden Ranking and the US News Best Global Universities, along with numerous national and regional tables. Each publishes its own methodology and each weights different things. Whichever you consult, read the methodology page before the results page, because the ordering only means what the indicators behind it mean.
One thing is common to all of them. Academic reputation, the single largest component in the QS table, is a survey asking academics to nominate institutions demonstrating academic excellence. It is a considered measure of scholarly standing. It is not a measure of whether the teaching on a particular master's programme is any good.
Why That Is a Weak Signal for One Student
Four reasons the overall table should not decide your choice.
They aggregate the whole institution. A university strong in medicine and physics can be ordinary in your subject, and the overall rank cannot tell you which. Subject-level tables are far more informative. QS publishes rankings across 55 subjects, and THE adjusts its methodology for each subject to account for differing research and publication cultures.
Research output is not teaching quality. A department producing heavily cited papers may be excellent to study in, or may teach undergraduates through overstretched staff. The correlation is real but loose, and it is weakest at taught postgraduate level, which is where most Indian students actually enrol.
Reputation surveys move slowly. They reflect standing built over decades, which favours older institutions and lags genuine improvement or decline by years.
None of it touches the things that determine your outcome. Rank position says nothing about whether the institution can sponsor your visa, whether its programme is eligible for post-study work rights, what the city costs, or whether India will recognise the qualification.
Be careful: A high ranking and a valid registration are unrelated things. Confirm status on the official register regardless of how well known the institution is, and never treat a ranking as evidence that the paperwork will work out.
What Official Quality Assurance Exists
Most destination countries run a statutory body that regulates higher education quality. These are the bodies whose judgement carries legal weight, and none of them produces a league table.
| Country | Official body or register | What it tells you |
|---|---|---|
| Australia | The Tertiary Education Quality and Standards Agency, and CRICOS registration | Whether the provider is registered and the course approved for international students. |
| New Zealand | The New Zealand Qualifications Authority | Quality assurance of providers and qualifications on the national framework. |
| United Kingdom | The register of licensed student sponsors, published on GOV.UK | Whether the institution can sponsor a Student visa at all. |
| Canada | The designated learning institution list, and the separate list of PGWP-eligible programs | Whether you can study there, and separately whether it leads to a work permit. |
| United States | SEVP certification, with accreditation required for the STEM OPT extension | Whether the school can enrol F students and whether the degree supports the extension. |
| Germany | The anabin database maintained by the Standing Conference of Ministers of Education | How institutions and qualifications are classified for recognition purposes. |
| India, on return | Association of Indian Universities equivalence | Whether the degree will be recognised for further study or public employment here. |

The Criteria That Should Replace the Ranking
Once official status is confirmed, these are the comparisons that carry real information.
- The actual module list. Read what is taught, week by week, not the programme summary. Two degrees with identical titles frequently teach different subjects.
- Who teaches and how. Class sizes, contact hours, whether assessment is by examination or project, and whether teaching is by permanent academics or doctoral students.
- Placements and industry links in your field. A required industry semester is worth more than several places in a table.
- Total cost in that city, including rent, which varies far more than tuition does.
- Graduate destinations for that specific programme, which many institutions publish, rather than institution-wide employment figures.
- Professional accreditation where your field is regulated, since that determines whether you can practise.
Those six comparisons take longer than reading a table, which is precisely why most applicants skip them and why doing them is an advantage. They are also the only comparisons that describe your experience rather than the institution's standing. A department with forty students in a seminar, a supervisor who answers email, and a placement in the industry you want will shape your two years far more than the difference between position 180 and position 240 in a global table.
How to Research a University Properly
- Confirm official status on the government register for the destination, before anything else.
- Read the subject-level ranking rather than the overall one, if you use rankings at all.
- Download the programme specification and compare module lists across your shortlist side by side.
- Look up three or four faculty members teaching the core modules and see what they work on.
- Email the department, not the admissions office, with two specific questions. The quality of the reply tells you something the tables cannot.
- Find graduates from that programme and check what they are doing now, particularly Indian graduates from recent years.
When Rankings Are Genuinely Useful
They do have legitimate uses, and it would be unfair to pretend otherwise.
For doctoral study, research standing matters directly, because you are joining a research group and citation intensity is a reasonable proxy for its activity. For employers in some markets, particularly in consulting and finance, institutional reputation carries weight in shortlisting. And for a student with no starting point at all, a subject table is a reasonable way to assemble an initial list of twenty institutions to investigate properly.
What rankings cannot do is finish the job. They are a way of generating a shortlist, not a way of choosing from it. The work that follows the shortlist is where the decision is actually made.
Compare destinations and their costs on the country comparison, explore what is taught in each field under programs, and follow changes to registers and rules on Maha Study Abroad news. The Government of Maharashtra endorses no institution and publishes no ranking, as set out in the Honesty Promise.

Frequently Asked Questions
Do global university rankings measure teaching quality?
Only indirectly and only in small part. In the QS World University Rankings, academic reputation carries 30 per cent and citations per faculty 20 per cent, so half the score reflects research standing. Faculty to student ratio, the indicator closest to teaching resource, carries 10 per cent. No widely used global ranking measures the quality of teaching on a specific programme.
What is the difference between QS and THE rankings?
They measure different things. QS publishes percentage weightings, with academic reputation at 30 per cent and citations per faculty at 20 per cent, so half the score reflects research standing, plus employer reputation at 15 per cent. Times Higher Education groups 18 indicators into five pillars covering teaching, research environment, research quality, international outlook and industry, and is aimed explicitly at research-intensive universities. The same institution can appear well apart in the two tables.
What should I check instead of a ranking?
Start with official status on the destination government's register, since that determines whether the visa and work rights are even possible. Then compare module lists rather than programme summaries, contact hours and class sizes, placement or industry links in your field, total cost including rent in that city, graduate destinations for that specific programme, and professional accreditation if your field is regulated.
Which official bodies regulate university quality abroad?
Australia has the Tertiary Education Quality and Standards Agency alongside CRICOS registration, and New Zealand has the New Zealand Qualifications Authority. The UK publishes a register of licensed student sponsors, Canada maintains the designated learning institution list plus a separate list of work-permit-eligible programs, and the US operates SEVP certification. Germany's anabin database classifies institutions and qualifications for recognition.
Does a highly ranked university guarantee a visa or work rights?
No. Ranking position and official registration are unrelated. A visa depends on the institution holding the right status, such as being a licensed student sponsor in the UK, and post-study work rights depend on separate criteria again, such as whether a Canadian programme is eligible for a Post-Graduation Work Permit. Check both regardless of reputation.
Are subject rankings better than overall rankings?
For most students, yes. An overall table aggregates an entire institution, so a university strong in medicine and physics may be unremarkable in your subject. QS publishes rankings across 55 subjects, and a subject table at least compares departments in the field you intend to study, though it still measures research and reputation more than teaching.
