Official employment-related Performance Indicators in UK Higher Education are based on the population of students responding to the First Destination Supplement (FDS). This generates potentially biased performance indicators as this population of students is not necessarily representative of the full population of leavers from each institution. University leavers not obtaining qualifications and those not responding to the FDS are not included within the official analysis. We compare an employment-related performance indicator based on those students responding to the FDS with alternative approaches which address the potential non-random nature of this sub-group of university leavers.
