There are many in East Asia who simply judge students on the basis of national tests. The top universities in the United States do not do that, and for good reason. We need a careful process for admissions that take all sorts of factors into account: different intellectual strengths, artistic expression, economic standing, social background, ethnicity, regional representation and designs a class as a balanced whole.

There are, however, many challenges to Asian universities. First, academic freedom, in all senses, is much more critical to the success of a university than how much money is spent on infrastructure or on hiring big names. Faculty need to have the space to pursue the research that they are passionate about and the also need to have the freedom to express their opinions in the university, and in the society as a whole.

That said, there are a few clear factors that determine the potential of a university to reach the highest levels of excellence. In the case of Harvard University, it was true that by the time of its tercentenary (300th anniversary of its founding) in 1936, Harvard had already achieved a reputation as a world-class institution. Harvard did not have the stature that it does today.

I suppose the situation varies from field to field. If you're a mathematician, your proficiency in English may not be such a problem. If you're in the humanities or social sciences, there is no doubt that it is a handicap for you.

The strong point of American research universities is the manner in which trustees, presidents and other senior executives retain a considerable amount of decision-making authority while at the same time maintaining a culture of open exchange and participatory debate.

Shared governance is often the critical element that is missing in Asian universities, no matter how talented the faculty may be. Either it is ministries of education that are trying to run things, or in private institutions - those who control the funds. Neither group knows much about teaching and research.

But, before we in America critique East Asia, we must also recognize that we are - unfortunately - taking on some of the same characteristics. Getting in the top institutions has become far more difficult and the value placed on one school over another in terms of education and careers has been much exaggerated.
