The NTU rankings, also known as the Performance Ranking of Scientific Papers for World Universities, began life in 2007 as a project of the Higher Education Evaluation and Accreditation Council of Taiwan (HEEACT), evaluating 500 international universities. Since then, it has expanded to over 1,000 universities and has been transferred to the National Taiwan University. In addition to the overall world ranking, NTU also publishes field and subject rankings. Data is derived from the Science Citation Index and the Social Science Citation Index.

The methodology is based on eight indicators grouped as follows:

Research Productivity (25% weighting); articles over 11 years, articles over one year

Research Impact (35%); citations over 11 years, citations over 2 years, average citations over 11 years

Research Quality (40%); h-index over 2 years, highly cited papers over 11 years, articles in high impact journals over one year.

Overall, the top five universities are Harvard, Stanford, University College London, Oxford, and Toronto. The top three universities in the various fields are:

Agriculture

2. Zhejiang University, China
