Admission competitiveness depends on the program and faculty. Some highly specialized programs, like medicine or engineering, may have more applicants than available spots. Strong academic performance, high grades, and a well-written motivation letter can significantly improve acceptance chances. For postgraduate applicants, relevant work experience, research experience, and recommendation letters strengthen applications. Proficiency in English or Croatian (depending on the program) is essential. Meeting all document submission deadlines and carefully following application guidelines is also crucial. Students can also enhance their applications by demonstrating extracurricular involvement and leadership experience.

Admission deadlines vary by faculty, but applications for the fall intake (October start) typically close around July/August, and for the spring intake (March start), they close in December/January. The process includes submitting an online application, uploading required documents (transcripts, diplomas, proof of language proficiency, etc.), and, for some programs, taking entrance exams or attending interviews. After receiving the acceptance letter, international students need to apply for a visa, arrange accommodation, and attend orientation. It's essential to check individual faculty websites for updated deadlines and specific application requirements.
