To ensure success

Our goal is to help companies evolve and grow professionally, providing them with tools to become more competitive and develop their
employees’ skills.

We offer tailor-made training ...

We know that every organisation has specific needs.

We like to take on new challenges and adapt to each client.

A dedicated account manager

We assign a single account manager to administer the entire training project for each organisation and be the sole interlocutor with the client’s training manager.

Progress assessment

Student progress is monitored several times a year, with the teacher evaluating each language area.

Monitoring and reports

Monthly and final reports are issued to follow up on the training. Comprehensive attendance monitoring: this is done daily in the classroom through our Interlang Air platform via computer, smartphone, and/or attendance sheets.

Satisfaction surveys

We assess students' opinions through satisfaction surveys. Two are given during the training period, one at the beginning and another at the end.


We provide excellence ...
We're experts

Our value is human capital. Our teachers are native or bilingual university graduates, graduates, qualified and experienced in teaching their language, and experts in different teaching formats: face-to-face, virtual, telephone, etc. They are also experts in analysing the needs of each student and the group and in establishing individual and shared objectives.


There are no borders ...
we're digital

We have our own platform, Interlang AIR, to which students can connect as and when they like. We offer a unique learning environment, combining digital content and a variety of learning methodologies.


Our own content

Classes can have a general focus, working
on all aspects of the language in a structured, progressive
way from a professional approach (communication skills, management, etc.) and at the same time address the interests and professional needs of each student so that they can perform better in their job.

Interlang has its own Content Development team whose
goal is excellence and originality. The online digital format
of the content makes interactive use accessible directly from our platform Interlang AIR,
with some elements also available in hard copy. The student has a variety of topics
in each category:

General topics: society, economy, art, culture, psychology, …

Business communication skills: presentations, negotiations, networking, meetings, …
