The Estonian Intensive Language Courses (ESTILC) are financed by the Estonian Ministry of Education and Research.
The ESTILCs give ERASMUS students the opportunity to study Estonian language and culture for three weeks. The courses are free of charge for ERASMUS students. However, fees may be charged for excursions and similar optional events and for other charges that ERASMUS students normally may be asked to pay. More detailed information is given in the course description.
Organising institutions and course descriptions can be found on the website of Estonian National Agency.
