Hi Ricardo, if you have a points layer (e.g. for school locations) and a polygon layer you may count the number of points (schools) that are located in each polygon with: Menu 'Vector' > analysis tools > Count points in polygon. Choosing this opens a dialog where you can choose your input layers (polygon and points), an attribute name for the points count and a name and path for the new file that is created.
