Few notions seem to capture the imagination of education policymakers today as completely as digitalization and leadership. Through these two, schools are believed to become transformed, and in turn, these transformed schools will transform people and society. This paper critically analyzes a Swedish official digital policy instrument that materializes digitalized school leadership practice. The policy instrument is made available as a "helpful tool" by a Swedish official education agency. The paper scrutinizes the policy knowledge process set to work within the instrument by the agency. Particularly, how the instrument may influence people to come to know and change schools, and how responsibility and risk of digitalization in schools seems to first be transferred to, and then between, people in schools. The paper is concluded by a discussion of how: (a) three knowledge phases interact in the knowledge process of the instrument, (b) the technical -- rather than social -- solution that digitalized school leadership practice is found to be, and (c) implications for digitalization in schools as a social, cultural and historical phenomenon of interest to research.
