A revised curriculum in Sweden is currently presented as a part of a lifelong learning. The intention is clear; work at preschool has to focus on knowledge. The National Agency for Education, NAE, shall support the implementation of the revised curriculum and this support is evaluated. As part of the evaluation a selection of managers in public and private preschools were interviewed. Among the questions were how they perceive the support, if the implementation has started, what consequences the implementation has and what obstacles there are for a successful implementation. A deeper reading of the results was used to trace if any side effects could be found in the answers. Further on the results were also to discuss whether the evaluation in itself could cause any side effects. The discussion is based upon earlier research and discussions concerning ethics, role of evaluator and Guiding Principles for Evaluators from AEA.
