The awards are highly competitive. On average, about 10% of the reviewed applicants are selected for awards in any given year. However, the number of offers in each discipline does vary from year to year and is not necessarily an indicator of the number of fellowships that will be offered in that discipline in subsequent years. The table below shows the total number of applicants, the total number of offers, and the percentage of fellows overall in each discipline over the past nine years.
