English immersion in London: a turning point for a company in the international financial sector
This project perfectly illustrates the added value of language immersion training. In response to an urgent need to improve their English skills, a company in the international financial sector opted for this intensive, targeted approach. The result: rapid, concrete and lasting progress for employees exposed to frequent international exchanges.
The need
Against a backdrop of constant exchanges with international contacts, a company specializing in the settlement-delivery of securities transactions identified a key challenge: to rapidly improve the level of English spoken by a priority group of staff who regularly interact with clients and colleagues abroad. The aim was to go beyond simple operational English, and gain greater fluency, confidence and impact in exchanges.
Our solution
To meet this strategic need, we deployed a full immersion training program in London, in partnership with a center renowned for its linguistic expertise.
Employees could choose between several formats:
- One-to-one lessons for tailor-made support,
- Group courses to encourage interaction and collective intelligence,
- or mixed formulas, combining the two approaches.
Each path has been co-constructed with management, to ensure optimum alignment with each individual's professional objectives.
Target language
English
The results
The effects of immersion were visible very quickly:
- Enhanced fluidity of expression,
- Increased confidence in speaking,
- Ease of communication in an international context.
In addition to the linguistic benefits, participants also emphasized the richness of intercultural interaction, having the opportunity to exchange ideas with professionals from other countries.
In view of these very positive results, English immersion is now fully integrated into the company's language training policy.
