Research signals the importance of promptly identifying and responding to emerging absenteeism, to prevent severe and chronic absenteeism. Prompt identification and response relies upon a good system for recording, reporting, and using data related to students’ school attendance and absence. The current article provides an overview of law, policy, and practice in the Netherlands regarding the recording, reporting, and use of school attendance data. We then consider the ways in which current law, policy, and practice help and hinder the work of school personnel as they endeavour to promote attendance and reduce absenteeism. Thereafter, we propose modifications to current policy and practice that could enhance the prompt identification and response to emerging absenteeism. When school personnel have easy access to reliable attendance data, and when they become accustomed to using the data to inform their work to promote attendance and respond to absenteeism, they are in a stronger position to support positive developmental outcomes among young people.
