Actiris case study: corporate language training Brussels

How Actiris transformed corporate language training for a multilingual Brussels workforce

Brussels is a city that switches languages mid-sentence. Walk through any Actiris office and you'll hear French, Dutch, English and Arabic in the space of a single conversation. For the people who work there, this isn't background noise. It's the job.

Helping people find work in a city this multilingual takes more than goodwill. It takes language confidence, in the precise vocabulary of recruitment, social services, employment law and human conversation. That's the world Actiris lives in every day, as the public employment service of the Brussels-Capital Region.

So when they came to us four years ago, they didn't ask for a language course. They asked for something harder: a programme that would actually move people forward in the work they were already doing.

Here's what we built together.

The challenges we inherited

When Semantics took over the contract, the programme needed a meaningful reset. Earlier screenings had been carried out by too many different assessors using passive testing criteria, which meant groups arrived already mismatched. Teaching had drifted toward the generic, designed for nobody in particular. Attendance had dropped off. Most participants weren't coming back after a single session.

What was unusual was the way Actiris went about choosing a new partner. Rather than running the public tender as a race to the bottom on price, they invited suppliers in to present their actual vision and approach to corporate language training first. We were one of them.

That conversation changed everything.

What the programme actually looks like

Three formats. Four languages: Dutch, French, English and German. All of it built around how people use language at work, not around what fits neatly into a textbook chapter.

Group courses for teams.

Four to six participants per group. 36 hours over six weeks. Two three-hour classes a week. Designed for levels A0 to B1.1, running three times a year. Taken consecutively, a complete beginner reaches solid intermediate level in twelve months. No magic. Just intelligent design.

Immersion duo courses.

One week. Five consecutive days. Four hours a day. Two participants, no more. Built for B1.1 and above, where the real goal isn't grammar but fluency under pressure. Small enough to customise around job-specific vocabulary and Selor exam preparation, which carries a meaningful salary bonus when passed.

Individual coaching for senior staff.

Reserved for management and the genuinely tricky linguistic profiles. One of our participants grew up in Brussels, spoke Arabic at home, French socially, and was schooled entirely in Dutch. Sounds native in French. Isn't, the moment you look at written grammar. That kind of profile doesn't slot into a group. It needs a coach, not a textbook.

What changed, in practice

Active testing from day one, applied uniformly across every assessor. Groups that made sense from the start. Teaching that was active rather than academic. Teachers we recruit and retain to our own exacting standards. Materials that look like the work people actually do.

Students also gained access to Mr Mentor, our proprietary e-learning app. It follows the structure of each class so people can keep practising at home, with speaking and listening drills powered by AI. Five minutes on the bus. Ten minutes between meetings. The practice fits the day.

And students started coming back. Session after session. Word travelled. New participants arrived because colleagues said the courses were worth it. The programme grew from inside Actiris, on its own merit. Not from a sales pitch.

In their own words

"I thoroughly enjoyed and learned a great deal from the French course. The content was practical, tailored to our work environment, and met our previously formulated wishes and needs. Victoire was, and is, a very pleasant teacher: attentive, never pushy, never didactic, and very caring. It was a pleasure to take lessons from her."

What this means for your team

Actiris isn't a special case. It's what happens when corporate language training is built around the work people actually do, rather than a generic syllabus delivered to a room full of strangers.

If your team has been through language training and you don't have much to show for it, the people aren't the problem. The approach is.

Semantics Belgium has been building tailored corporate language training for professional teams in Brussels and across Belgium since 2010. Get in touch for an honest conversation about what better could look like for your team.
