How often is the ISEE offered in Switzerland each year?

The ISEE is typically offered several times throughout the year in Switzerland, although available dates depend on the test level (Lower, Middle, Upper) and the calendar of each local test center. Most Swiss families aim to take the test between October and January to meet U.S. private school application deadlines. But here’s the catch: Switzerland doesn’t have nearly as many test dates as the U.S., and seats can fill up fast—especially in Geneva, Zurich, and Lausanne.

We recommend starting early and booking a date as soon as your application strategy is in place. Don’t wait until December to realize January’s test dates are full. At Cardinal Education, we help you map out a full prep timeline: when to start tutoring, when to schedule mock exams, and how to time your official test date for maximum readiness and minimum panic. With the right schedule, your child can feel calm, prepared, and one step closer to a standout application.
