The 2022 "OECD Skills Strategy Implementation Guidance for Flanders, Belgium: Faces of learners in Flanders" report identified nine distinct adult learner profiles. In 2023, the Flemish Government decided to work with the OECD on a follow-up project to develop a screening tool that enables the assessment of how actual adults compare against the profiles. This technical paper provides a description of the context, methodology and outputs of the screening tool, and a short discussion of its potential applications.
