BlueSky Ranking of Computer Science Rankings 2023

The world’s four biggest technology companies by market capitalisation – Apple, Microsoft, Google and Amazon – all have at least one founder that studied computer science at a U.S. university. Whether or not they finished their undergraduate studies – think Steve Wozniak and Bill Gates – or walked away from their Ph.D. – Larry Page and Sergey Brin – is another matter.

And four U.S. universities – MIT, Stanford, Carnegie Mellon and UC Berkeley – dominate the top of the international league table for Computer Science in 2023. If you want to be a global leader in the IT industry, you need world-class institutions such as these to develop the talent and research that are essential to innovation.

Though the U.S. accounts for 70%, or 35 of the world’s top 50 technology companies by market cap this year, U.S. universities account for only 40%, or 20 of the world’s top 50 for computer science in the BlueSky Ranking of Computer Science Rankings 2023.

China, which is home to tech giants that include Tencent, Alibaba and JD can claim 7 schools in the top 50 of the BlueSky Thinking ranking. There are 10 others that make the top 100 in the individual rankings of US News and ARWU.

The UK is next with five universities, followed by Australia and Canada with four each. As so often, Singapore and Switzerland demonstrate that having populations of less than 6 and 9 million respectively has not prevented them from playing in the big league, each with two world-class institutions for computer science.

The BlueSky Ranking of Computer Science Rankings compiles the performance of schools across the four major global subject rankings published every year by Times Higher Education (THE), QS, US News and ARWU (Shanghai). Each of them uses a different methodology and measures different things with the inherent limitations of each assessment, so doing particularly well in one ranking and less well in another is reflected in the overall average score.

We’ll be generating more subject-specific rankings in the coming months. And you can also check out our global and regional rankings of university rankings.

University Subject Rankings Methodologies

Each of the major university rankings uses a different methodology and weights the use of different data to produce their league tables, so it is important to understand what is being measured. In simple terms:

THE – the performance indicators are grouped into five areas: Teaching (the learning environment); Research (volume, income and reputation); Citations (research influence); International Outlook (staff, students and research); and Industry Income (knowledge transfer).

Teaching (30%); Research (30%); Citations (30%); International Outlook (7.5%); Industry Income (2.5%).

QS– six indicators looking at four broad categories: research reputation, the learning and teaching environment, research impact, and internationalisation. 

Academic Reputation (40%); Employer Reputation (10%); Citations per Faculty (20%); Faculty Student Ratio (20%); International Student Ration (5%); International Faculty Ratio (5%)

ARWU – considers every university that has any Nobel Laureates, Fields Medalists, Highly Cited Researchers, or papers published in Nature or Science. In addition, universities with a significant amount of papers indexed by Science Citation Index-Expanded (SCIE) and Social Science Citation Index (SSCI) are also included.

Quality of Education (10%); Quality of Faculty (40%); Research Output (40%) Per Capita Performance (10%)

US News – calculates the rankings using 13 indicators and weights that U.S. News chose to measure global research performance.

Global Research Reputation (12.5%); Regional Research Reputation (12.5%); Publications (10%); Books (2.5%); Conferences (2.5%), Normalized Citation Impact (10%); Total Citations (7.5%); Number Of Publications Among 10% Most Cited (12.5%); Percentage Of Total Publications Among 10% Most Cited (10%); International Collaboration – Relative To Country (5%); International Collaboration (5%); Number Of Highly Cited Papers Among Top 1% Most Cited In Respective Field (5%); Percentage Of Total Publications Among Top 1% Most Highly Cited Papers (5%)
