Where the facts on this list come from, and how they are checked
Where the facts come from
We read each provider’s website and record what it says about its offer for children: ages, the weekly timetable, prices and the period they cover, languages, trial classes and whether a parent must stay.
Addresses, map positions and opening hours may also come from the provider’s Google Maps listing, and a club’s membership of a sports federation from the club list that federation publishes. A provider with no website of its own can be listed from its Google listing alone when the listing itself says it is for children; its page then shows only the address and opening hours.
With every fact we keep the address of the page, the date we read it and a short quote in that page’s language. Guides, news sites, booking platforms, social media and reviews are never a source.
Source labels
Every source carries one of three labels: ‘published by the provider’ (its own website), ‘Google listing’ (its Google Maps profile) or ‘federation club list’ (the list of member clubs a sports federation publishes).
On a provider’s page the label and the date sit beside each fact, so you can see where it comes from and how old it is.
Facts that are not published
When the pages we read leave a fact out, the provider’s page says ‘not stated’ and the table shows a dash. ‘Not stated’ describes our sources, not the provider.
Nothing is filled in by guesswork. A school stage such as the kleuters (the two infant years) or the bovenbouw (the upper years of primary school) is not turned into an age, and neither is a swimming certificate. A price keeps the period the provider gives; the one calculation we make is the ≈ price per lesson: a package or course price divided by its number of lessons.
Class times and opening hours
The table has two time columns. Class times: the days and hours of a lesson, a care afternoon or a camp day, as the provider gives them. Opening hours: when the venue is open, often from its Google listing.
A venue can be open at an hour when no group runs for a given age. A row with opening hours only goes below the line, under a heading that says why.
The after-school pages look at school days from 14:00 to 18:00. Hague primary schools on a continuous timetable finish around that start time; schools on the traditional timetable finish around a quarter past three, and on Wednesday around noon. A class counts if one of its groups starts within that span; for a group early on Wednesday afternoon, set the Time filter earlier. Care counts if its hours, extended care included, cover the whole span.
What we do not judge
- No provider, teacher, coach or programme gets stars, a score or a rank.
- We do not visit providers; every fact rests on a published source.
- We do not judge how well anyone teaches, coaches or cares for children.
- We do not track free places or waiting lists; ask the provider.
- Prices appear as the provider publishes them, with period and date; we do not confirm them with the provider.
Right of reply
If you work for a provider on the list and a fact is wrong, missing or out of date, send the right one through the form, with a link to the page where it appears.
A correction that the provider’s own pages confirm goes into the next update and is noted in the logbook. A provider that closes keeps its page, marked ‘closed’, and leaves every table.
You can also ask for the provider you work for to be taken off the list: choose ‘Take a provider off the list’ in the form and leave a contact that shows you write on its behalf. The provider, its page and its rows in the data files are removed within a month.
Dates and updates
Each provider’s sources are read again within 6 months. Prices for a period that has passed stay on the provider’s page with that period; the filters and the summary line no longer use them.
How the site is paid for
Providers pay nothing to be listed, and no payment changes a row or its position, which follows the same rules for every provider, as set out under each table.
A provider’s page may carry one link, marked as such, to Zartrace, a service connected to this list. Clicks on contact buttons are counted as totals only, with no personal data.
Open data
Download the whole list as JSON, one record per provider, or as CSV, one row per programme. Both files hold every source, label and date, and state their licence.
Districts, distance and the map
Districts are the parts of The Hague parents name, each inside one of the city’s eight stadsdelen (boroughs): the smallest statistical wijken are joined to a neighbour, and two names stand together where parents use both, as in Statenkwartier - Duinoord and Bohemen - Waldeck. Voorburg and Leidschendam are one district each, and so are Rijswijk and Wassenaar. An address in Delft, Westland or Pijnacker-Nootdorp is filed under that town. An address belongs to the district whose boundary it lies inside; a beach club or surf school on the sand belongs to the district behind it.
Distance is a straight line from the point you choose to the nearest address, 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; district boundaries from the CBS Wijk- en Buurtkaart of Statistics Netherlands.
