I have lost my preference form. What should I do?

You can download a new blank preference form from the Amsterdam School Boards (BBO) site and print it out, or pick one up at a primary school. When submitting the preference form, you must submit valid proof of address. A valid proof of address is, for example, a purchase deed, rental contract, an extract from the Basic Registration of Persons (BRP) or the shelter contract or something similar.
