IGCSE Highest Mark in the World

ISF International School Frankfurt Rhein Main is proud to announce that Rishabh Agarwal (Grade 11) has received the Outstanding Cambridge Learner Award for achieving the highest mark in the world in Cambridge IGCSE Foreign Language German. This exceptional accomplishment is a testament to Rishabh's dedication and to the strength and impact of ISF's German program.

Rishabh began German as a beginner in Grade 7 at ISF and, within just a few years, reached a level of mastery that placed him at the very top worldwide.

“We are incredibly proud of Rishabh,”said Mr. David Harrison, School Director at ISF. “Achieving the world's highest mark is a rare distinction. The fact that Rishabh started German as a beginner in Grade 7 underscores the effectiveness of our approach: daily German for every student, whether native speaker or learner, combined with high expectations, targeted feedback, and consistent support.”

Dr. Dirk Solies, Head of German at ISF, added: “Our program blends daily practice, clear skill progression, and rich cultural experiences. Rishabh's success demonstrates that with structure, motivation, and tailored guidance, students - regardless of their starting point - can achieve outstanding results.”

At ISF, all students receive daily German lessons, with pathways designed to challenge native speakers and to support international learners in steadily building advanced proficiency. Native competence is preserved and extended academically, while non-native learners gain a clear route to high levels of fluency - bringing advantages in school life, university readiness, and future careers.

ISF is part of the SABIS® Network, which has been preparing students for academic success worldwide for over 140 years. ISF's German program benefits significantly from the SABIS® educational philosophy - structured learning, systematic skill building, frequent formative feedback, data informed performance monitoring, and a strong “no gaps” culture that secures lasting progress. These principles shape ISF's approach across subjects and contribute to high achievement, as exemplified by Rishabh's award.
