Organiser
Nederlandse Wiskunde Olympiade.
Route
School first round → regional second round → national final → international training programme and team-selection tests → IMO.
How to enter
Ask a school mathematics teacher to enter the first round. The standard entry group is havo/vwo classes 1–5; the organiser also documents wildcard routes. The final and international training occur across school years, so preparation and selection can span more than one season. Round-by-round guide, current organisation and team-selection news
For cross-border schooling, home education or national-team eligibility, read the shared eligibility guide and obtain the national organiser’s ruling.
Past papers and solutions
The second-round archive pairs opgaven with uitwerkingen and reports. The organiser notes that the final was called the second round before 2010. Use the competition archive navigation for first-round and final papers, rather than treating all second-round labels as equivalent.
Previous results
Dutch results and reports covers the domestic programme. For international appearances, medals and contestant records, use Netherlands in the official IMO archive. A national-round award and an IMO medal describe different achievements.
