Vensters PO (link to Dutch-only site) is a project whereby statistical information relating to primary schools is gathered within a single system. This information includes data on educational yields, pupil populations, finances and staff. Vensters PO provides school boards and schools with a reliable basis from which to work on enhancing the professionalism of their organization (e.g. with a view to improving yield) and for dialogue about their teaching with the various stakeholders: parents, local authorities, the inspectorate, etc. The data recorded in Vensters PO relates to schools and school boards and are acquired from DUO (Education Implementation Service), the Education Inspectorate and the schools themselves (multiple use of data). Vensters PO processes the data into meaningful formats and feeds it back to schools and school boards.
