Citizenship Test Neuchâtel 2026 – Prussian Legacy Canton Guide

Neuchâtel is refreshingly precise about its knowledge test. Every candidate is questioned orally on their knowledge of Switzerland during the interview at the COSM, the cantonal service for multicultural cohesion. The test has 16 questions – four per theme across geography, history, politics and society – with at least one question per theme about Canton Neuchâtel itself. You pass with at least 10 correct answers, and partial answers count as wrong.

The best part: the canton publishes the complete question pool as a downloadable questionnaire (current edition June 2026, available with and without answers), and states explicitly that those questions represent the entirety of what can be asked. Prepare from the source, and drill Neuchâtel-specific questions here until the pass is comfortable.

Ordinary-naturalisation candidates are exempt from the knowledge questions if they can show one of three things: at least five years of compulsory schooling in Switzerland; a Swiss upper-secondary (secondary II) diploma; or participation in the dedicated course "Vivre en Suisse et à Neuchâtel", which the canton runs in Neuchâtel and La Chaux-de-Fonds – its attestation replaces the test in principle.

That third route is worth knowing about, with two caveats from the canton: the course ends with its own exam, which you can retake once before falling back on the COSM test, and registration already requires proof of French at A2 written and B1 spoken. The attestation exempts only ordinary-naturalisation candidates, not facilitated ones.

The base rules: a valid C permit at filing, 10 years in Switzerland of which 3 within the 5 before the application, and 2 years of domicile in the canton. Years spent in Switzerland between ages 8 and 18 count double, with a minimum of 6 actual years; B and C permits and DFAE legitimation cards count in full, F permits at half.

Two particularities are easy to miss. First, if you have lived in a registered partnership with a Swiss citizen for at least 3 years, 5 years of residence in Switzerland suffice instead of 10. Second, applications can be filed individually from age 9, as a family, or as a partial family – minors are in principle included in their parents' application.

The required level is B1 spoken and A2 written, evidenced by a fide language passport. You do not need one if French is your mother tongue, if you attended compulsory school in French for at least five years, if you completed upper-secondary or tertiary education taught in French, or if you hold a DALF, DELF, TCF or TEF certificate.

Neuchâtel adds a warning from experience that is worth taking seriously: obtaining the language passport and having your civil-status data verified can take a while depending on your situation. Do both early, before assembling the rest of the dossier.

Neuchâtel publishes its fees exactly, per dossier and regardless of how many people it covers. The cantonal fee is CHF 650 for a dossier filed by a minor, CHF 1,500 for an adult, and CHF 1,900 for a couple – married, in a registered partnership, or cohabiting for at least 3 years at the same address. The communal fee adds CHF 150 for individual applications or CHF 200 for joint ones, and the federal fee runs between CHF 50 and 150.

Beyond fees, the integration conditions apply: taxes paid up, no open debt-enforcement proceedings, a clean criminal record (convictions in the VOSTRA register within the last 10 years can justify refusal), no social assistance during the procedure or the 3 years before, and support for your family's integration. Neuchâtel explicitly weighs personal circumstances – disability, illness or other serious personal reasons – where these criteria cannot be met; the evidence is yours to provide.

The cantonal fee is due in full when you file with the Service cantonal de la population; if the file is closed before it goes to the Confederation, CHF 300 (150 for minors) stays due and the rest is refunded. The order is then fixed by the LDCN: the COSM enquiry with the oral test, the conseil communal of your commune, which decides within three months on the proposal of its naturalisation commission, the federal authorisation from the SEM, and finally the Conseil d'État, which grants cantonal citizenship. Children included in a parent's application pay nothing at cantonal and communal level.

Since at least four of the sixteen questions concern the canton, Neuchâtel's remarkable history is exam material. This is the canton that was simultaneously Swiss and a Prussian monarchy from 1815 to 1848, freed itself in the bloodless republican revolution of 1 March 1848, and gave the world its watchmaking capitals – La Chaux-de-Fonds and Le Locle, UNESCO World Heritage for their urban horological planning.

Work through the official June 2026 questionnaire first, since it is the complete pool. Then rehearse answering out loud: this test happens in conversation at the COSM, not on paper, and spoken fluency with the answers is what carries the interview. Contact for the course and materials: COSM, Place de la Gare 6, 2300 La Chaux-de-Fonds. For the application itself: Service cantonal de la population, secteur des naturalisations, Rue de Tivoli 28, 2002 Neuchâtel, 032 889 41 41, naturalisation@ne.ch, reception by appointment only. Practise the Neuchâtel questions before the interview.
