In this paper we explore datafication through a specific kind of evaluative practice in Swedish early childhood education and care (ECEC): the creation of quality reports by individual preschools. A theoretical framework is developed based on Dahler-Larsen's descriptions of three 'evaluation imaginaries' (the modern, reflexive modernity and audit society), with elaboration of their respective characteristics and complementary notions from other sources. We then apply the framework, and a qualitative text analytical approach, to analyse eight quality reports from diverse Swedish preschools, purposefully selected to represent preschools that vary in terms of ownership, geographical location, size and pedagogical profile. We find that the reflexive modernity imaginary is most clearly influential in the ECEC quality reports, but there are emerging indications of the audit society imaginary's influence. We also find variations in prioritised focus in the reports among ECEC providers, underscoring the need for further exploration. The study calls for future research to delve into provider-specific nuances, expand the investigation to other kinds of evaluations and scrutinise the broader implications for ECEC operations and practices.
