Article 14 of the St. Gallen citizenship act requires you to be familiar with Swiss and local conditions: you take an interest in public affairs, know about them and take part, know the principles of the structure of the state and have basic knowledge of geographic, historic, political and social conditions. The naturalisation council establishes these facts and holds the naturalisation interview with you. Neither the act nor the ordinance says how the knowledge is tested; the canton notes that some naturalisation authorities run a written or oral test.
In practice most St. Gallen communes require the civics test of Arge Integration Ostschweiz, some together with its civics course; Arge lists the requirements of 26 communes. The test is written, lasts about one hour and costs CHF 120; sittings take place in St. Gallen, Goldach, Rapperswil-Jona, Uznach and Wil. The sample questions show open and matching tasks in six areas: geography, history and languages, democracy and federalism, rights and duties, social security and health, work and education, and the Canton of St. Gallen, for instance which river flows through the canton to the North Sea or at what age women and men receive the old-age pension.
In the City of St. Gallen every person aged 15 or over who is included in an application must have passed the Arge test before the application is filed; the certificate may be at most two years old, and the city does not accept tests from other providers such as the Migros Klubschule. Since 4 September 2026 the two naturalisation councils waive the test for applicants under 18 who attended all three years of upper primary school in Switzerland, because the relevant knowledge is taught there. From the age of 18 the test must be taken in every case.
You can pass the test long before you meet the residence periods; the city explicitly recommends taking it early and working on your German in the meantime. If you fail, you register for one of the next sittings. To prepare, Arge offers its civics course in six modules and teaching material on the canton and its regions. Even with the test passed, the naturalisation interview remains: there the council wants to hear that you connect the knowledge with life in your commune.
