The OLS language assessment is compulsory for all participants partaking in an Erasmus+ or European Solidarity Corps mobility for studies, traineeships or volunteering in another Programme Country and having one of the following languages as the main language of instruction, work or volunteering (except native speakers).
The first language assessment is to be taken before the mobility period and the final language assessment is to be taken at the end of the mobility period.
For Higher Education students, it is also a prerequisite to the mobility. The sending institution/organisation can decide whether to make the payment of the final instalment of the financial support subject to the completion of the final OLS language assessment, at the end of the mobility. This should be specified in article 6.3 of the grant agreement.
