The École Suisse Internationale regularly supports diplomats, international executives and multicultural teams wishing to improve their French for specific professional uses.
This is how École Suisse Internationale helped a group of diplomats gain fluency and confidence in professional French communication.
Background
In May 2025, École Suisse Internationale was approached by a group of foreign diplomats based in Paris. Each held roles requiring regular interaction with French counterparts in multicultural and high-level professional environments.
Their objective? To express themselves fluently in official conversations and to better grasp the nuances of diplomatic French and international relations vocabulary.
The Challenge
Abroad, diplomatic services are aware that fluency in French is essential for working in Francophone countries. Indeed, the diplomatic world is highly codified and requires precise terminology. Speaking fluent French is therefore crucial for diplomats who wish to gain confidence and credibility in their professional interactions.
They were looking for a programme that combined:
- In-depth grammar reinforcement
- Intensive speaking practice
- Specialised vocabulary in international relations and geopolitics.
Our Teaching Approach
Following an individual interview with each participant, our teaching team created a bespoke programme tailored to their level, professional goals and availability.
The course structure combined:
- Group sessions to build spontaneity and interactive skills
- Mini-groups focused on diplomatic French,
- One-to-one lessons for focused work on specific challenges
- Final group session: role-playing at an embassy during a day promoting their country
The materials, adapted to each level, mostly consisted of authentic written documents (newspaper articles, books and manuals on international relations) and oral documents (radio broadcasts and video reports).
The Results
After one month of training, participants reported significant improvements in both oral confidence and spontaneity. Several noted a better understanding of cultural subtleties in diplomatic exchanges, contributing to more effective communication in their roles.
