A place is guaranteed to children living in Nes aan de Amstel; how does that work

Children to whom De Zwaluw is the nearest (priority) school are guaranteed a place at this school, provided that:

1. De Zwaluw was chosen as the school of first preference;
2. The enrolment has been completed in time (no later than the closing date);
3. The enrolment is accompanied by a valid proof of address (a proof or the pre-printed enrolment form)
