In Sweden, adequate digital competence has been put in the spotlight due to the Swedish 2017 national strategy for the digitalisation of the K-12 school system. Based on both policy and practice, the aim is to explore teachers' enacted digital competence in three upper secondary schools in Sweden and thereby provide an empirical account of what the notion 'adequate' means in practice. The data consists of interviews with teachers and classroom observations. At an aggregated analytical level, the results are presented as four narrative sub-case descriptions. It is concluded that teachers' adequate digital competence is flexible in meaning, determined by local contextual conditions and enacted in activities and decisions that are based on the teachers' own value frameworks. The understanding of 'adequate' in this study does not appear to be clarified in the formulations used in the national strategy.
