If you grew up with Dutch at home but your writing is shaky, the fastest route is usually a course that places you at B1 or B2 and then drills grammar and written accuracy, not one that starts at greetings. Intensive one-to-one training and university NT2 tracks tend to rebuild grammar quickest. Group courses work well too, provided you take a placement test first and tell the teacher exactly what is weak.
What is actually weak, and why it matters
Heritage speakers often understand a lot and speak passably but freeze on paper. Word order in subordinate clauses, the difference between hen and hun, die and dat, and consistent verb spelling are the usual gaps. A general beginners course wastes your time on vocabulary you already know. What you want is a course with a level test, a clear grammar syllabus and written homework that gets corrected.
Before choosing, decide what you need Dutch for. If it is daily life and family, B1 is a sensible target. If it is study or a professional role, B2 is the usual bar. The path finder can help you narrow the field, and the full directory lists everything we track.
Courses that rebuild grammar fast
Regina Coeli in Vught and Eindhoven runs intensive one-to-one training. For a heritage speaker with uneven skills, that format lets a teacher target your grammar gaps directly instead of following a fixed syllabus. It suits professionals with a clear deadline and the budget for intensive work. It does not suit anyone who needs a slow, cheap evening routine, and you should check the provider for price and schedule.
Radboud in to Languages in Nijmegen offers university-level NT2 courses, including intensive summer programmes. The academic framing suits people heading for HBO or university study, and the grammar coverage is thorough. Less useful if you only want conversational Dutch for family visits.
KU Leuven ILT in Leuven runs intensive and regular NT2 courses across levels 1 to 6, with a summer option and an academic focus. If you are based in Flanders, or willing to travel, this is one of the strongest structured routes for rebuilding written Dutch. It is a heavier commitment than a weekly class.
INTT at the University of Amsterdam teaches B1 and B2 NT2 for highly educated professionals, with a strong exam preparation focus. Good if you intend to sit an NT2 exam or need academic Dutch. Not aimed at people who want a relaxed introduction.
Group courses and exam routes
Direct Dutch Institute in The Hague has taught highly educated expats and professionals since 1985, at A1 to B2. The teaching is solid and the levels are clearly separated, which helps if a placement test puts you at B1. It is a general professional course rather than a heritage-specific one, so say upfront that your speaking outstrips your writing.
Babel Utrecht is known for Business Dutch and NT2 preparation at A2 to B2. Practical and work-oriented. Fits people whose Dutch needs to function in a Dutch workplace. Less relevant if your goal is academic writing.
Linguapolis at the University of Antwerp offers intensive daytime and evening NT2 courses from A1 to C1, with an academic focus. The evening option suits people working full time in Belgium.
If an exam is required, Staatsexamen NT2 is the official State Exam. Programma I is B1, for work and vocational study. Programma II is B2, for higher education and many professional roles. Many jobs and citizenship paths ask for it. Check the official source for whether your situation requires it, and see our NT2 preparation section.

Official requirements, briefly
Under the 2021 Civic Integration Act, the standard route is B1, with exams in reading, listening, writing and speaking plus KNM. A municipality can allow A2 after substantial effort, and older obligations used A2. For naturalisation the language requirement is A2 in 2026, with a move to B1 planned but no confirmed start date. Rules change, so check the official source and our inburgering pages before planning around them.
Practical next steps
Take a placement test before booking anything. Tell the provider your situation in one sentence: Dutch heritage, strong listening, weak writing. Ask whether written work is corrected and how much grammar is taught explicitly. If you prefer one-to-one help, browse Dutch tutors; verified Pro tutors have 3,000 or more lessons and a 4.9 or higher rating on their platform. If you are choosing a city first, see cities.
How we know this: the options come from The Dutch Directory listings checked on 2026-10-19, and fit scores are editorial, not user ratings.
