OLS is an acronym for "Online Language Support" (Apoio Linguístico Online, in Portuguese).
It is a free online language learning platform designed for participants of Erasmus+ and the European Solidarity Corps.
Through the OLS platform, students or recent graduates who intend to undertake an international internship can test their level of language proficiency, which they will use during their stay abroad. Based on the results, they can follow a free online course to strengthen their language skills.
Before mobility: It is recommended that beneficiaries take a language proficiency test.
At the end of mobility: Beneficiaries should take a language proficiency test to assess their progress in the language used during the mobility.
