This article is based on studies carried out within the "Young children's learning" research education programme. This undertaking involved five graduate students, all recruited from the Swedish preschool system. The licentiate thesis makes up the final product of their education programme, and the focus of each candidate's licentiate thesis was preschool-level documentation. Using the results of all five theses, a re-analysis was conducted with the concept of normality as the common starting point. The purpose was to investigate whether documentation and assessment can change the view of normality in preschools, and furthermore, what consequences there may be for preschool activity. 'The narrow preschool and the wide preschool' is the model used to support the analysis, which is a model used in previous studies to review and discuss educational choices and conditions in the school system. Results of the present investigation show that the documents and assessments performed in preschool have a strong focus on the individual child and a traditional, school-oriented learning is highly valued. The documentation and assessment practices that take place now in our preschools, therefore, most likely influence the preschool view of normality and restrict the acceptance of differences.
