How Long Does It Take to Learn Dutch? Hours by Level

The figures on this page come from the US State Department and its Foreign Affairs Manual, the published hour estimates of Cambridge, LanguageCert and the Alliance Française du Yorkshire, two vocabulary studies, and the Dutch government and DUO, all read 2026-10-31. Where the sources disagree, the page shows both numbers instead of averaging them into one.

How long does it take to learn Dutch?

It takes an English speaker roughly 24 weeks of full-time training, at 23 class hours a week, to reach ILR level 3 (General Professional Proficiency) by the US State Department’s estimate, and about 350 to 400 hours of lessons to reach B1 by exam boards’ and course providers’ estimates for English and French. Those are the two numbers most answers quote. Neither is a promise, and they measure different things: one counts weeks in a government language school, the other counts lesson and homework hours.

For someone with a job and evening lessons, the honest unit is years. The table puts the main estimates side by side; the sections below explain each one and where it stops applying.

The estimates agree on months of full-time training or hundreds of hours of lessons, but only the State Department’s figures are for Dutch itself; the CEFR hour estimates were measured on English and French.

What does the FSI say about how long Dutch takes?

The US State Department’s language school lists Dutch at 24 weeks, in Category I, the group with the shortest courses for English speakers. Category I runs from 24 to 30 weeks (552 to 690 class hours), and a typical week is 23 hours in class plus 17 hours of self-study, so by that arithmetic Dutch’s 24 weeks mean about 552 class hours and about 960 hours of work in all. The goal is an integrated score of 3, speaking plus listening, on the Interagency Language Roundtable scale (State Department, Foreign Language Training, read 2026-10-31).

The Foreign Affairs Manual tells a slightly different version. Section 3 FAM 3911.2 (revised 2023-07-17) lists “24 Weeks” for Italian, Portuguese, Romanian, Spanish, Danish, Dutch, Norwegian and Swedish and 30 weeks for French, measured to level 3 in speaking and reading (3 FAM 3910, read 2026-10-31). The State Department page measures speaking and listening and puts Spanish at 30 weeks, while the manual says speaking and reading and puts Spanish at 24; Dutch is 24 weeks in both.

Level 3 on the Interagency Language Roundtable scale is named General Professional Proficiency; for reading, it describes someone who reads authentic prose on unfamiliar subjects at normal speed and understands almost all of it (ILR reading scale, read 2026-10-31). A 2020 National Academies report on the Foreign Service Institute confirms that the typical training goal is ILR level 3 in both speaking and reading (National Academies, 2020, read 2026-10-31).

Two cautions apply. First, the 24 weeks are a course for Foreign Service employees, whose job during those weeks is learning the language; the figure does not transfer to an evening class. Second, many articles quote 600 to 750 class hours for Category I. That figure comes from earlier versions of the same State Department page (archived copy, 2023-06-01, read 2026-10-31), which also listed Spanish at 24 weeks. The current page gives 552 to 690 class hours.

How many hours does each CEFR level take?

No official Dutch source this page found publishes hours per CEFR level. The estimates that exist come from exam boards and course providers for English and French: about 90 to 100 hours to A1, 180 to 200 to A2, 350 to 400 to B1 and 500 to 650 to B2, counted from zero. The French figures are the nearest proxy for Dutch, because the State Department rates Dutch as quicker than French for English speakers (24 weeks against 30). The Cambridge and LanguageCert figures are for learners of English from any native language, so they show only the general size of the effort, not how long Dutch takes an English speaker.

The three providers agree closely up to B1 and drift apart above it. Cambridge’s figures (Introductory Guide to the CEFR, 2013, read 2026-10-31) and the Alliance Française du Yorkshire’s (FAQ, read 2026-10-31) are cumulative from zero. LanguageCert publishes an estimate for each level on its own rather than cumulative totals (LanguageCert, read 2026-10-31); the LanguageCert column below adds them up so the three can be compared.

What counts as an hour matters. Cambridge defines guided learning hours as lesson time plus the tasks a teacher sets, LanguageCert as hours under the guidance or supervision of a teacher or training provider, and the Alliance Française du Yorkshire counts hours of instruction. Time spent on your own, outside anything a course sets, is not in these numbers, which is one reason a learner who reads, listens and reviews words daily can move faster than the table suggests. Cambridge adds its own caveat: learners vary in how long they take, for many reasons.

How many Dutch words do you need for each level?

There is no agreed number, and this page found no study that gives a Dutch vocabulary size for each CEFR level. The best-known per-level estimates are for English and French: Milton and Alexiou (2009, as reported in their GALA 2010 paper) associated A2 with about 1,500 to 2,500 English words and B1 with about 2,750 to 3,250, while French learners reached the same levels with fewer words. For Dutch itself, one study put the receptive vocabulary needed for university study at about 10,000 base words.

The per-level figures come from the X-Lex test, a yes/no test that samples the 5,000 most frequent words of a language and estimates how many of them a learner knows (Milton and Alexiou, GALA 2010, read 2026-10-31). The table shows how much the language changes the answer. The authors present the figures as indicative rather than as requirements for each level. Because the test only counts words among the 5,000 most frequent, it underestimates total vocabulary at every level, and the English C2 range reaches the test’s maximum. The Greek column is different in kind: it gives the mean scores of four class groups (12 to 19 students each) at one university language school, and the authors note that those groups were not strictly separated by level.

The Dutch-specific figure answers a different question. Hazenberg and Hulstijn tested native Dutch first-year students and non-native students and concluded that “the minimal vocabulary size needed for university studies is 10,000 base words.” They also measured an average of about 18,800 base words for the native-speaking freshmen, and argued that earlier Dutch estimates of 3,000 or 5,000 base words were too low for that purpose (Applied Linguistics 17(2), 1996, abstract read 2026-10-31). The two sources do not conflict so much as answer different goals: everyday independence on one side, reading academic Dutch on the other.

How long does inburgering give you to learn Dutch?

If you have a civic integration requirement under the Wet inburgering 2021, you have 3 years to complete the civic integration process, and the B1 route aims for B1 within that time. EU/EEA and Swiss citizens, and people in the Netherlands temporarily for work, study or an exchange, have no such requirement. The Dutch government states both points on its civic integration page, which also links to applying for an extension of the period (government.nl, read 2026-10-31).

On the B1 route, the municipality can lower the level to A2 only after at least 600 hours of language lessons at a school with the Blik op Werk quality mark, which the municipality checks (DUO, page updated 2025-04-02, read 2026-10-31). Who decides, for which skills, and how your level is set in the first place are covered in inburgering: A2 or B1. If you are aiming at study or skilled work rather than integration, the Staatsexamen Nt2 and the inburgeringsexamen are different exams with different levels.

How long does it take an expat to learn Dutch part-time?

For an expat studying alongside a job, the realistic range for B1 is about one to two and a half years, depending almost entirely on weekly hours. The table divides the providers’ B1 range (350 to 400 hours) and B2 range (500 to 650) by common study rhythms. It is arithmetic, not a forecast, and it assumes every hour counts the way a guided hour does.

At 6 hours a week or less, B2 takes about two years or more; at 10 hours it is just over a year.

Three things move a learner up or down that table. Your native language and earlier languages: the State Department’s estimates are for English speakers, and its own categories show how much the distance between languages matters, since the same department sets 88 weeks for Arabic, Chinese, Japanese and Korean against 24 for Dutch. Daily contact with Dutch outside class, from letters, colleagues, radio and shop conversations, adds hours that no table counts. Consistency: the hour estimates assume steady study, and a course with long gaps loses part of each gap to forgetting.

Where PolyYapp fits

PolyYapp covers one part of the timeline: Dutch vocabulary. PolyYapp brings each Dutch word back on a spaced-repetition schedule and drills it with 5 exercise types, from about 3,900 Dutch words (as of October 2026), with text-to-speech audio in a Netherlands Dutch voice. PolyYapp is free to download and use, with no in-app purchases and no ads today, and no account is needed to start. The research on spacing reviews is set out in how to learn Dutch words.

PolyYapp does not shorten the rest of the timeline. It is not a full course: it has no grammar lessons, no speaking practice and no exam mode, and it does not sort words by level. PolyYapp runs on iPhone and iPad, and on Apple-silicon Macs as the iPad app, with no Android version, and it needs an internet connection. For choosing the course that does the rest, see the best apps to learn Dutch, which compares full courses with vocabulary tools.

What this page could not confirm

Two kinds of number that circulate widely are left out on purpose. No Dutch government or Taalunie source was found that publishes guided hours per CEFR level for Dutch. And no study was found that measures Dutch vocabulary size at each CEFR level; the per-level word counts above are for English, French and Greek. Treat any single figure for Dutch that you see quoted without a source as a guess.
