If you’ve been thinking about studying a postgraduate course in the USA, the sheer size and scope can be daunting. Over 4,300 American higher education providers cater to the ever-growing population of students. Even though only around 1,000 of them offer Masters/PhD-level degrees (which narrows things down slightly) there's still a huge variety of institutions to choose from.

In this guide we talk about the different kinds of institutions, university organisations and some of the top picks for postgraduate study in the USA according to international ranking tables.

Graduate schools

Often existing as part of larger universities, graduate schools offer only Masters and PhD level qualifications. You may hear students go from ‘college’ to ‘graduate school’ (or ‘grad school’).

An individual university may have more than one graduate school, specialising in different subject areas. Some graduate schools focus on professional training like in Business, Medicine and Law. They may sometimes also be referred to as ‘professional schools’.

US university organisations

The US higher education system is home to various organisations and groups of universities, some of which are internationally famous. It’s worth knowing a little about organisations like this as you decide where you want to study in the USA.

The Ivy League

We may as well start with the big one! The Ivy League is probably the most famous university association in the world. Its name is shorthand for academic excellence and student prestige.

Formed of eight of the country’s highest-ranking universities, the Ivy League are some of the most sought after by students. However, you must remember that admission is highly competitive, and you shouldn’t think they are the be-all and end-all of American educational excellence. There are many top-ranking universities that aren’t members!

You can find more information on our Ivy League guide.

Public Ivies

The private nature of the Ivy League has led some top public universities in the US to be referred to as 'Public Ivies'. The Public Ivies aren't a formal association (and their 'membership' is completely unofficial), but the term is still a meaningful mark of respect.

The Association of American Universities (AAU)

The Association of American Universities is a membership organisation comprising leading public and private North American research universities. It includes 60 US institutions (including seven of the eight Ivies!) as well as two in Canada. In practice, the AAU is similar to the UK’s Russell Group. Membership serves as a badge of quality and allows universities to collectively lobby on higher education issues.

The Carnegie Classification of Institutes of Higher Education

The Carnegie Classification of Institutions of Higher Education system is based on the number of programmes US institutions offer at different levels, and the dominance of different subject areas in their research and training activity. The Basic Classification groups institutions according to the level and size of their degree programmes. Where a university offers postgraduate programmes, you can also use its Graduate Instructional Program Classification to see which disciplines predominate in its provision.

Domestic rankings of US universities

There are a wide range of domestic rankings that only include universities in the USA. Most are produced by American media outlets and similar organisations. Domestic rankings don't compare US universities internationally; instead, they rank US institutions against each other. While this is useful if you're narrowing your search to the USA, it’s less helpful if you're still comparing a range of options for postgraduate study abroad.

We haven't summarised specific US university rankings here, but significant examples include:

  • The U.S. News and World Report’s Best Grad Schools ranking looks at universities providing postgraduate ('graduate') qualifications in 12 broad fields.
  • The Washington Monthly National University Rankings doesn't produce a specific ranking of graduate schools, but its main rankings do consider each university's research performance in detail, making it more relevant to advanced degree programmes such as Masters and PhDs.
  • The America's Top Colleges ranking is published by Forbes magazine (an influential American business publication). This ranking focusses primarily on student-centred metrics such as satisfaction, academic success and graduation rate.
