Modern governments must increase their capacity for analysing and evaluating public programmes. Evaluations, however, take place in a political context and many policies have unstated political goals. Sweden appears to have a highly developed evaluation and effectiveness auditing system and the Swedish case is instructive, not only because of its experience in the evaluation field, but also because it illustrates the changing policy style. Two main agencies are involved in the evaluation process and they both experience some difficulties in their evaluation studies. These difficulties stem in part from the political environment in which they both operate but also relate to their own organisational styles. The resource squeeze could bring broad environmental charges which could be conducive to a greater influence for the two agencies.
