How the facts on this site are checked
Where the facts come from
We read each place’s own website and write down what it says about its offer for children: ages, the weekly timetable, prices with the period they cover, languages, trial lessons and whether a parent has to stay.
Addresses, map positions and opening hours may also come from the place’s Google Maps listing. For sports clubs, membership of a national sports federation may come from the club list that federation publishes.
Each fact is kept with the address of its page, the date it was read and a short quote in that page’s language. Directories, news articles, booking platforms, social media and reviews are never used as sources.
Source flags
Every source carries one of three flags: published by the place (its own website), Google listing (its Google Maps profile) or federation list (the club list of a sports federation).
On a place’s page the flag and the date stand next to each fact, so you can see at once where it comes from and how old it is.
Facts that are not published
When the pages we read leave a fact out, the place’s page marks it as not published and the table shows a dash. “Not published” is about our sources; it says nothing about the place.
Gaps are never filled by guessing. A school stage such as kleuters or bovenbouw is not turned into an age, and neither is a swimming diploma level. A price keeps the period the place gives; the only sum we make is the ≈ price per lesson, a package or course price divided by the number of lessons in it.
Lesson times and opening hours
Time has two columns in the table. Lesson times: the days and hours of a lesson, a care session or a camp day, as the place prints them. Opening hours: when the branch is open, often taken from its Google listing.
A place may be open at an hour when no group for a given age meets. A row with opening hours and nothing else is listed under the dividing line, below a heading that says why.
The after-school pages look at weekdays from 15:00 to 18:00. A lesson counts when one of its groups starts inside that span; after-school care counts when its hours, extended hours included, cover all of it.
What we do not judge
- We give no place, teacher, coach or programme a rating, a score or a rank.
- We do not visit places; every fact rests on a published source.
- We do not assess how well anyone teaches, coaches or looks after children.
- Free spots in a group and waiting lists are not tracked; ask the place.
- Prices appear as the place publishes them, with their period and date; we do not confirm them with the place.
Right of reply
Do you run a listed place and see a fact that is wrong, missing or out of date? Send the correct one through the change form, with a link to the page where it is published.
A correction that the place’s own pages confirm goes into the next update and is recorded in the update log. A place that closes keeps its page, marked as closed, and is taken out of every table.
You can also ask for a place you run to be removed: choose “Ask to remove a listed place” in the change form and leave a contact that shows you run it. The place, its page and its rows in the data files are removed within a month.
Dates and updates
The sources of every place are read again within 6 months. Prices published for a period that has ended stay on the place’s page with that period, but the filters and the summary line no longer use them.
How the site is funded
Listing is free for places, and no payment changes a row or its position, which always follows area and name.
A place’s page may carry one link to Zartrace, a service linked to this list and marked as such. Clicks on contact buttons are counted only as totals, with no personal data.
Open data
You can download the whole list as JSON, one record per place, and as CSV, one row per programme. Both files hold every source, flag and date and state their licence.
Areas, distance and the map
Areas are Amsterdam’s wijken, the neighbourhoods the city keeps its statistics by, under the names parents use: the Jordaan, the Transvaalbuurt, the Rivierenbuurt. Wijken that people only name together form one area (De Pijp, IJburg, Watergraafsmeer), and the smallest ones, harbours and office parks for the most part, are joined to a neighbour. Around the city the areas are the municipalities, such as Amstelveen, Diemen and Zaanstad, plus Badhoevedorp, the village parents name rather than Haarlemmermeer. A branch is filed under the area whose boundary contains it, or under Badhoevedorp when it lies close to the village centre.
Distance is a straight line from the point you choose to the nearest branch, rounded to half a kilometre. Your location is asked for only when you press the button, and it stays in your browser.
A position worked out from an address is approximate. Map data © OpenStreetMap contributors; wijk boundaries from the City of Amsterdam’s open data.
