Language remains the single most cited obstacle to student and youth mobility across the European Union, and the Online Language Support platform exists precisely to address that gap. Built into the Erasmus+ and European Solidarity Corps programmes, OLS gives participants preparing to study, work or volunteer abroad a structured way to assess and build the language skills they will need once they arrive.
What the platform actually does
OLS combines two functions: assessment and instruction. Before departure, participants take a language assessment that measures their current proficiency in the language of their host country or institution. This is not a pass-or-fail gate - a lower score does not disqualify anyone from participating. Instead, it generates a personalised learning pathway, directing users toward the specific skills and vocabulary most relevant to their upcoming placement. For higher education students on mobility stays of 14 days or longer, taking this assessment beforehand is a formal requirement, with exceptions made for native speakers or other justified cases.
Once enrolled, participants can access online courses covering any of the languages OLS supports, with no cap on how many languages or study units they work through. The courses rely on interactive exercises rather than static reading material, and they remain available both before departure and throughout the mobility period itself, allowing continuous reinforcement rather than a one-off preparation exercise.
Who can use it, and in which languages
Access is not limited to university exchanges. The system covers a broad span of the Erasmus+ and European Solidarity Corps ecosystem, including:
- Higher education mobility
- European Solidarity Corps placements
- Vocational Education and Training (VET)
- Adult learning, and staff across Education, Training and Youth fields
- School-based mobility
- Youth exchanges
Language coverage extends across all official EU languages, from Bulgarian to Swedish, and additionally includes the official languages of other Erasmus+ and European Solidarity Corps programme countries - Icelandic, Macedonian, Norwegian, Serbian and Turkish. Where a destination's primary language falls outside this list, sending or receiving organisations are expected to arrange alternative linguistic support directly.
Why this matters beyond the classroom
Preparing someone linguistically before they relocate is not simply a courtesy - it has direct bearing on how well that person integrates, performs academically or professionally, and stays safe in an unfamiliar environment. Participants who arrive with even a working grasp of the local language are better positioned to navigate housing, healthcare, workplace instructions and everyday bureaucracy without depending entirely on others. For programmes moving thousands of young people across borders each year, that preparation reduces friction for both the individual and the host institution.
The design also reflects a broader policy goal written into Erasmus+ itself: promoting linguistic diversity rather than defaulting to a single lingua franca. By supporting all EU languages equally, rather than concentrating resources on the most commonly spoken ones, the programme signals that mobility should not implicitly favour speakers of larger languages over smaller ones.
Access and next steps
OLS is not something participants sign up for independently. Access is granted through the sending institution or coordinating organisation, which issues a link with instructions once a participant has already been selected for mobility. Anyone with questions about eligibility, timing or language availability should raise them directly with that sending body, or with the relevant National Agency, rather than searching for enrolment routes elsewhere.
After the mobility period ends, participants can take a final assessment to measure how much progress they made while abroad - a practical way of quantifying an experience that is often described only in general terms, and a useful data point for both the individual and the institutions tracking programme outcomes.
