Yes, it is increasingly common for A0-A1 Dutch courses to be taught mostly in Dutch, but it is not the only valid approach and it should not leave you unable to follow. A good beginner course uses Dutch as the main language but supports it with clear visuals, repetition, English explanations when needed, and checks that everyone understands. If you were promised you could follow with no prior Dutch and now feel lost, that is a legitimate concern, not a personal failing.
Why do providers teach beginners in Dutch? Many language schools believe that immersion from day one builds listening skills and confidence, and it can work well when the teacher is skilled at grading language and using gestures, pictures, and simple Dutch. However, research and best practice suggest that for absolute beginners, some mother-tongue or English support is often helpful, especially for grammar explanations and instructions. A 95% Dutch class can be appropriate if the teacher constantly checks comprehension and uses English sparingly but effectively. It is not appropriate if students are confused and the teacher does not adapt.
What you can do:
Talk to the teacher or coordinator. Explain that you were told no prior Dutch was needed and ask whether they can provide brief English explanations or written summaries. Many teachers will adjust if they know.
Ask for the course plan and materials. See whether the first weeks include supported Dutch or assume prior knowledge. If the materials are all in Dutch with no glossaries, that is a sign the course may be pitched too high.
Consider your learning style. Some learners thrive in immersion; others need more scaffolding. Neither is wrong. If you are spending most of the class lost, you are not getting the input you need to progress.
Evaluate alternatives. Look for courses that describe their approach clearly, such as "Dutch with English support" or "immersion with English for grammar." Ask about the teacher's experience with absolute beginners. A short trial lesson can tell you a lot.
Supplement your learning. Even in a Dutch-only class, you can prepare vocabulary and phrases beforehand. Apps, flashcards, and beginner videos can help you keep up. If you want structured support, Dutch Fluency is one option among many, but check that it matches your level.
Honest tradeoff: A Dutch-only class can accelerate listening if you are ready for it, but it can also slow you down if you are not. The key is whether the teacher adapts and whether you feel you are learning. If after a few more classes with adjustments you still cannot follow, it is reasonable to switch to a course with more English support. Your goal is progress, not endurance.
