How is the distance to priority schools calculated?

The distance is calculated by the Research, Information and Statistics Agency (OIS) of the City of Amsterdam using the established school database. The calculation is made based on Open Street Maps (OSM) and the Large-Scale Topography Registry (BGT). These are used to calculate walking distances between residential addresses and the schoolyard entrance. This calculation method is more accurate than that of, for example, Google Maps.

The calculations are made by the OIS once a year between July and September. The calculation remains valid for an entire school year. Even if there are interim changes, such as the construction of a bridge. Unless a school is closed. The distances shown are binding, unless there has been a deviation from the agreed calculation method due to an error.
