The purpose of this thesis is to examine how the Swedish public sector, exemplified by a Swedish municipality, evaluates its managers. With the support of scientific research it proposes possible solutions to improve the evaluation of managers across the public sector. The municipality is located in western Sweden. Senior management has contributed to this thesis by providing access to senior managers across different divisions within the municipality. The study has been performed by conducting personal interviews with eight senior managers. The interviews were structured and all of the managers were asked a series of nine standardised questions. Using their initial responses they were then asked a series of individual questions based upon their answers to the nine standardised questions. The results of the study shows that whilst the municipality has created routines for the evaluation of its managers it does not always evaluate the formal part of management. Almost all of the interviewed managers have experienced flaws with the current methodology. They made several suggestions to improve the process. Using existing research, the study was also able to highlight potential flaws with the evaluation process and suggested several ways to improve upon current practices.
