Case Study: EBZ Business School achieves secure, GDPR-compliant online exams and uninterrupted student assessment with Mercer Mettl

EBZ Business School’s digital journey amid the disruption

EBZ Business School, Germany’s premier university for real estate management studies, faced the sudden need to move on-campus exams online amid the pandemic while meeting strict GDPR rules, supporting diverse question formats (diagrams, math, coding), providing a German-language interface, enabling human proctoring, and offering 24/7 support. After evaluating options, EBZ chose Mercer Mettl’s online examination platform to address these urgent requirements.

Mercer Mettl implemented a GDPR-compliant solution with AI-assisted and human proctoring (each proctor monitoring fewer than 30 students), a lockdown browser, German-language UI, low-bandwidth resilience, auto-grading and dedicated support channels; the university digitized its exams in under two months. The platform maintained educational continuity, enabled remote exam-taking without compromising security, and delivered measurable impact — Mercer Mettl’s AI flagged over 95% of cheating instances and the system significantly reduced manual grading and administrative effort.
