KDE – Cantonal German test in the naturalisation procedure in the Canton of Zurich

The constitution of Canton Zurich requires adequate knowledge of the German language from all those who wish to become naturalised. Proof of language competence must be provided.

The Municipal Office of the Canton of Zurich has developed the Cantonal German Test in the Naturalisation Process (KDE), which ensures a legally compliant language assessment. Academia Integration is certified by the Canton of Zurich to conduct the KDE for naturalisation applications.
The test assesses listening and speaking skills at level B1 and reading and writing skills at level A2 of the Common European Framework of Reference for Languages (CEFR).


The listening, reading and writing sections together take about 1.5 hours. The speaking part takes about 15 minutes. No aids (e.g. dictionaries, mobile phones) are allowed. KDE participants must bring a valid identity document with them to the examination.

Regular naturalisation: Those who are already in the naturalisation procedure will receive a letter from the municipality of residence allowing him/her to take the examination.

Simplified naturalisation: Those wishing to naturalise can register independently at any time.
The deadline for registration is 10 days before the examination date.

The test results will be communicated to the participants within 2 weeks.
