The present study focuses joint school and university development work in preschool-projects try to increase educational quality. The aim of this study was to explore perceived conditions and perceptions of projects among participants in development projects in eleven preschools. In addition, we were interested in the perceived outcomes of the projects. All projects were aimed at strengthening the preschool principal’s and staff’s competence regarding children’s language and emergent literacy development. The studied projects lasted up to three years. The results are based on phenomenographical analyses of thirteen focus group interviews with principals and staff, including eighty-eight participants, during the project period. Follow-up interviews were conducted with twenty-four representatives from the participating preschools one year after the closure of the projects. The interviews were transcribed and analyzed. Field notes from visits in the preschools contributed to the empirical material. Our findings indicate that the perceptions of a project, contributed to the understanding of a project as loaded with expectations that the development project is limited in time and that it will add extra-curricular work demanding extra resources, which led to the perception that when the project is over, development work is over. The word project, thus, per se functioned as a limiting factor, if on-going development work, was aimed for. Lack of anchoring the development work in the local context was perceived as problematic, with effects for the participants’ experience of agency. Furthermore, difficulties in managing large staff turnover during the project was perceived to cause the development work to come to a stand-still. Active leadership, and shared responsibility were perceived as favorable factors for the progress of the development work. Our conclusions encompass participants’ perceptions of adjustment to the local context, shared responsibility and seeing development work as exceeding time limits as vital components of successful development work.
