Principal & Leadership Team

Leadership & Governance
German International School Sharjah is led by Principal Sven Hertner, who also teaches History and Sports in the secondary school — a hands-on leadership style that reflects the school's tight-knit, community-oriented character. Hertner is supported by a well-structured senior team: Vice Principal Viktoria Rüffer, Head of Secondary Patrick Täuber, Head of Primary Valentina Zieglowski, Head of Kindergarten Carolin Kreiling, and Head of GIB Oguz-Han Alkan. This breadth of phase-level leadership is notable for a school of just 251 students. [MISSING: principal tenure start date — length of service in post not confirmed in available sources.]
The school's 2023 SPEA inspection rated overall effectiveness as Good — a meaningful step up from its previous rating of Acceptable in 2018, demonstrating sustained improvement under the current leadership direction. Inspectors specifically credited the leadership of the principal and senior leaders in establishing a positive teamwork culture and highlighted the strong partnership with governors and parents that supports school improvement as key strengths. Governance sits with a Board of Governors chaired by Mansour Haisam, with board portfolios covering finance, facilities, HR, and parent liaison — a structured model for a non-profit institution. The school is also financially and operationally supported by the Federal Republic of Germany through the Central Agency for Schools Abroad in Cologne, providing an additional layer of institutional oversight uncommon among Sharjah's private schools.
At the time of the 2023 inspection, the school employed 25 teachers with zero teaching assistants, producing a teacher-to-student ratio of 1:8 — significantly more favourable than the Sharjah city average of 1:13.6 across all private schools. For parents, this translates into smaller classes and more direct teacher contact time. However, the inspection also recorded a teacher turnover rate of 25% — a figure that warrants attention. One in four teachers left in the year prior to inspection, which can disrupt continuity of learning and institutional knowledge, and inspectors implicitly flagged self-evaluation processes as an area requiring stronger staff involvement. The main nationality of teachers is German, consistent with the school's curriculum and language of instruction.
Teaching quality was rated Good overall by inspectors, who observed 128 lessons across the four-day review. The inspection noted that the overall quality of teaching is a key strength, though it also identified consistency as an area for development — specifically calling for teaching to reach a very good or better level more reliably across all subjects and phases. Parent engagement is embedded in governance, with board member Mona El Baz holding a dedicated parent and PR portfolio, and parent surveys forming part of the formal SPEA review process. The school's improvement trajectory — from Acceptable to Good in five years — signals that leadership vision is translating into measurable outcomes, even if the journey to Very Good remains ongoing.
