An independent market study is currently being conducted to assess whether there is a need for a new primary school in the Strandeiland area (part of IJburg, a new neighborhood under development in Amsterdam). This study is being carried out by Planzo, a trusted and experienced research agency, on behalf of AMOS Onderwijs.
You are receiving this letter because your address has been selected to take part in the study. The selection was based on publicly available data and statistical profiles. We do not know who lives at your address, and we do not have access to personal information such as names or ages.
Why is your participation important?
It is crucial that enough people respond to this survey. This ensures that, once the neighborhood is fully developed, there will be a sufficient and diverse range of school options for young children. Your input helps make this possible!
What do we ask of you?
We kindly invite you to complete a short online questionnaire. In the questionnaire you will be asked, among other things:
- The survey takes just a few minutes (approx. 3–4)
- Your answers will be processed completely anonymously
- Participation is possible until Saturday 11 October 2025
Your privacy is protected
Your address was selected once-only based on general characteristics, by a third party approved by DUO (the Dutch national education agency). We do not store any personal information, and you will not be contacted again. All responses are processed fully anonymously.

Why did you receive a letter?
Your address was selected for this research campaign using public and statistical data. We do not have your name or any personal information. You were selected based on anonymous characteristics like your neighborhood and housing type.
We do not know who lives at your address, and we do not use or store personal data.
This address selection was carried out using segment data provided by Whooz, a company that specializes in neighborhood profiles and statistical targeting. You have received this letter because your address appears relevant for this research — but we cannot see or verify who the resident is.
What data do we use?
Planzo only uses:
- postal addresses (street, house number, postal code, city),
- once — to invite people to participate in this research,
- without storing or linking to any personal data.
Your answers in the questionnaire are fully anonymous and cannot be linked to you or your household. You will not be contacted again, and your address is not added to any database.
