FAQ
Have some questions?
If you have a question that is not listed below or wish to have a chat, feel free to reach out to us at any time.
[email protected]Do I need to speak Croatian?
No. All COA programs are conducted in English. Croatian people are also very internationally friendly and can adapt to new people easily, so you won’t need to be fluent in Croatian in order to explore the cities and our culture.
Is there an age limit in order to apply?
There are no age limits in order for you to participate in COA programs. The average age of participants is between ages of 19 to 36, but we accept musicians based on their potential, not age.
Are accommodation and food included in my tuition?
Accommodation will be provided for you in the city of Varaždin or Novi Marof, depending on production location. As for your meals, they are not included in your tuition. You can find more information about what’s included in your tuition here.
What if I am not sure which role to apply for?
