A guide to the methodology for the QS World University Rankings
The QS World University Rankings is the world’s most read university ranking. The main ranking – launched in June each year – is used by governments, students, parents and the wider higher education sector as a key point of comparison when making decisions. However, one of the main questions we get asked is how the Rankings actually work. Here, we’ll explore the methodology in detail.
How QS ranks universities: Lenses, Indicators, and weightings
The Rankings are compiled by our data analysts, in partnership with higher education institutions and trusted partners. Each Ranking – be that the flagship QS World University Rankings, our regional rankings, our Subject Ranking, or Sustainability Ranking – uses a bespoke methodology. You can learn more about the full Rankings suite here.
In this article, we will be focusing on our flagship – the QS World University Rankings.
To rank institutions, the QS World University Rankings uses Lenses, which is a group of related Indicators, and Indicators, which are measurements of one aspect of an institution’s performance.
As you can see, 50% of an institution’s QS World University Ranking position is based on the Research and Discovery Lens, comprised of our Academic Reputation (30%) and Citations per Faculty (20%) Indicators.
20% of an institution’s position is based on its performance in the Employability and Outcomes Lens. This Lens is made up of Employer Reputation (15%) and Employment Outcomes (5%).
Institutions can submit data by QS HUB. If you do not yet have login details, contact our Help Desk
How we measure Employer Reputation and Academic Reputation
Employer Reputation and Academic Reputation measure the reputation of an institution among key stakeholder groups – employers and other academics. The QS World University Rankings are the only ranking to include an institution’s employer reputation. The majority of undergraduate students leave university in search of employment after their first degree, making the reputation of their university amongst employers a crucial consideration.
The data for these two crucial Indicators is provided by the QS Global Employer Survey, and the QS Global Academic Survey. Institutions can submit up to 400 contacts to QS for each of our surveys, and should be carefully selected by the institution. The survey is then distributed to these contacts by QS. The Global Employer Survey and the Global Academic Survey measure the reputation of global institutions, not necessarily just the institutions they have been nominated by.
Once the surveys have closed, the data will be cleaned and validated by QS to ensure that the responses we’ve received are valid, usable, and complete.
QS World University Rankings eligibility criteria
Not all higher education institutions are eligible for the QS World University Rankings, and not all eligible institutions proceed to be ranked. In the flagship QS World University Rankings, only around 1,500 institutions are ranked to ensure data quality, though we assess over 8,000 as part of a usual cycle.
QS World University Rankings eligibility criteria
To be eligible for the QS World University Rankings an institution must:
- Offer full-degree programmes at both undergraduate and postgraduate level
- Offer full-degree programmes in at least two faculty areas
- Offer full degree programmes in at least two subjects in each faculty area
- Have at least three graduated classes in each subject
- Deliver all or part of each programme on campus
To be included in the QS World University Rankings an institution must:
- Be in the top 20% of institutions globally for Academic Reputation
- Have at least 100 papers indexed and published by Scopus over a five-year period
- Be ranked in its respective regional ranking (Asia, Arab Region, Europe and Latin America and the Caribbean only)
Small Institutions
If an institution has fewer than 5,000 students, in the Indicators Academic Reputation, Employer Reputation and Citations per Faculty at least one of the below must be true:
- Be in the top 1,000 for one of the above
- Be in the top 1,200 in two of the above
- Be in the top 1,300 globally
The QS World University Rankings methodology summarised
The QS World University Rankings methodology combines reputation evidence, research performance, and employability outcomes into a weighted framework designed to compare institutions globally. By structuring the ranking around lenses and clearly weighted indicators, QS aims to make the drivers of overall performance transparent, while eligibility thresholds help ensure institutions are compared on a broadly consistent basis.
Understanding how each indicator is weighted, and how overall performance is calculated, is key to interpreting results, identifying strengths and gaps, and prioritising the data and stakeholder engagement that most directly influence ranking performance.
