Graduates work in banking, consulting, ICT and logistics, or continue to a master’s. You receive a joint BSc in Business Engineering.

Entry requirements for Irish students

• A school qualification from an EEA country is accepted if it gives access to a similar programme in that country. No specific Leaving Cert grades are published, so your file is assessed individually by KU Leuven’s Admissions Office.
• Maths matters most here. All applicants take the faculty’s free online maths test and upload the result, and everyone sits a maths assessment on campus at the start of Year 1. A score under 40% suggests you may not be ready. We suggest Higher Level Leaving Cert maths.
• English: students whose secondary education in Ireland was entirely in English are exempt. Otherwise IELTS 6.5 (6.0 per skill), TOEFL iBT 90 or CAE/CPE.
• No Dutch or French is required. The extra maths proof (AP or SOWISO) applies only to non-EEA diplomas.
