The Dutch Directory

What The Dutch Directory covers: listing counts by type, the Verified Pro count, doctrine and endpoint URLs. Call it when you need to know the scope of the directory before searching.

{
  "type": "object",
  "properties": {},
  "additionalProperties": false,
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Search every way to learn Dutch: schools, universities, apps, podcasts, exams and online tutors. Use it when someone asks where or how to learn Dutch. Filters: city (Dutch or Flemish, e.g. Utrecht, Den Haag, Antwerpen), type, goal (e.g. inburgering, NT2, business, conversation), cefr, online, verified_pro, platform, kind. Each result has directory_url and primary_url to cite.

A short list of the best-fit options for a city and goal, ranked by editorial fit score (not paid). Use it when someone wants a few recommendations rather than every option. A Dutch Fluency item always comes with independent alternatives.

Also says where the basic civic integration exam abroad (inburgering, level A1) is taken for a country: the Dutch embassy or consulate, or the country to go to when it is not held there (capital.civic_exam). Pass a capital (e.g. Tokyo) or an ISO country code (e.g. JP). With no arguments, lists the capitals that have a local option. Use it when someone lives outside the Netherlands and Belgium or asks about Dutch classes, the CNaVT exam, the civic integration exam abroad or a Dutch school in another country.
