Gifted students who volunteer or are selected by teachers are trained to become Shadow Teachers®. Shadow Teachers exist in each subject and grade level, learn material a week ahead of their classmates, and may lead the class under teacher's supervision.
Advisory Classes start in Grade 4 with weekly sessions that provide a safe space to discuss topics important to students' lives, including health and well-being, IT safety, and cultural understanding. In the early years, topics include peer pressure, organizational skills, personal hygiene, health and exercise, conflict resolution, problem-solving, time management, and exam preparation techniques. Students have access to counselors who address personal and academic issues individually or in groups, supporting their social and emotional development. The SABIS Student Life Organization (SLO) offers clubs and activities that promote social engagement and teamwork. Health and wellness are supported by resident nurses who provide medical care during the school day and manage emergencies, as well as ongoing care for students with health needs.
Learning Support is an essential part of the SABIS Educational System. Student progress is monitored, and when learning gaps form, the school team—including teachers and administrators—works to fill the gaps through additional support channels at the school. The support is offered through teacher-led study groups and by assigning Prefects and Group Leaders to foster responsibility and engagement. The Academic Department of the SABIS Student Life Organization (SLO) provides peer tutoring, Power Study Sessions, and academic competitions, as well as On-Demand Tutoring videos to support learning. These provisions help students access learning and achieve their academic goals.
English is the language of instruction. German is taught daily as either Regular German (based on the Hesse curriculum) or as Foreign Language German (beginner, intermediate, or advanced). The German program completes the main curriculum and reinforces what is taught in English and math, including colors, numbers, letters, and sounds. Celebrating the host country, the Primary School German program also incorporates traditional songs, rhymes, games, and festivals. German is offered as part of the core Primary School curriculum.
Advisory Classes cover topics related to health and well-being, IT safety, cultural understanding, interview skills, and career counseling as students mature. Student Counseling is available to support students individually or in groups to address personal and academic issues and promote resilience. ISF has resident nurses who provide medical care during the school day, manage emergencies, and support students with ongoing health needs. The framework fosters mental wellbeing and social development through structured programs and access to guidance. These services help students cope with challenges and build coping skills.
