What is Access known for in research?

The fields where it stands highest, over all time, ranked among every institution above the floor in each field.

Each strip is that field's whole ranked pool, with the notch where Access sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).

Which fields of science does Access work in?

In 2022-now, 96% of research at Access is in Physical Sciences, 3% in Social Sciences. Its largest fields are Engineering (60%), Materials Science (27%), Physics and Astronomy (3%). It does 2.2× the world's share of Physical Sciences.
