The setting and use of targets in the public sector has generated a growing amount of interest in the UK. This has occurred at a time when more analysts and policymakers are grasping the nettle of measuring performance in and of the public sector. We outline a typology of performance indicators and a set of desiderata. We compare the outcome of a performance management system — star ratings for acute hospital trusts in England — with a productivity measure analogous to those used in the analysis of the private sector. We find that the two are almost entirely unrelated. Although this may be the case for entirely proper reasons, it does raise questions as to the appropriateness of such indicators of performance, particularly over the long term.
