Article 5 of the Graubünden citizenship act requires you to be "familiar with cantonal and communal conditions", and article 6 of the ordinance says what that means: basic knowledge of geography, history, politics and society, participation in social and cultural life and contacts with Swiss citizens. The citizens' commune checks this. Article 26 of the ordinance makes a naturalisation interview compulsory and requires it to be recorded; only in justified cases may the AFM release a commune from it. Whether a written test is held in addition is up to the citizens' commune. If it holds one, it must make sure that you can prepare with suitable materials or courses and that the test can be passed with the language skills required for naturalisation, that is B1 spoken and A2 written.
The Bürgergemeinde Chur, the largest in the canton, describes its procedure in five steps: applying, with the file going to the canton for foreign nationals; examination of the documents, the residence requirement and suitability, with preparation courses and a citizenship test; a personal naturalisation interview; the decision on the assurance of communal citizenship, cantonal citizenship and the federal authorisation; and finally the ceremony at which all new citizens receive their certificate of citizenship. In Davos the Bürgerrat of the citizens' commune decides on the assurance under the commune's naturalisation act of 28 June 2018. In Poschiavo, in the Italian-speaking south, applications reach the communal chancellery through the Ufficio della migrazione. Interview and test take place in your commune's language; the language proof can be given in German, Italian or Romansh.
The canton helps you study, but it also warns. Its information sheet refers you to your citizens' commune for the basic knowledge of Switzerland, the canton and your commune and recommends the reader "ECHO, Information zur Schweiz" published by HEKS. It states expressly that "citizenship courses" sold by private providers give no guarantee of covering the material asked for and that attendance certificates are not taken into account. The integration portal hallo.gr.ch explains what Swiss democracy rests on, which languages are spoken, how the political system works, what freedom of religion means and since when women and men have been equal before the law: the topics that also come up in the interview.
