Wellbeing

Social and Emotional Learning (SEL)

Universal screeners identify academic and social-emotional needs to guide tiered interventions. MTSS is led by four departments: Learning Support, English as an Additional Language (EAL), Counseling and Guidance, and Academic/College Counseling. The school emphasizes that all students can learn at high levels and integrates language development with wellbeing.

Special Educational Needs (SEN)
AISZ has a Learning Support team serving students with gaps in learning and with mild, moderate and intensive needs. The school does not provide services such as occupational therapy, physical therapy, educational psychologist testing or other intensive services. If a child's needs reach beyond AISZ's service capabilities, the school may refer and recommend external services at extra cost. If AISZ cannot provide adequate services for the student's level of English, admission may be declined.

English as an Additional Language (EAL)
AISZ has English Acquisition (EAL) teachers and assistants in both the lower and upper school. The EAL program is tailored to individual student needs. Prior to acceptance as a full-time student, students may be required to take the Versant English proficiency test to determine readiness. Support is provided with in-class and outside-of-class adjustments, and the level of support decreases as proficiency improves.

Mental Wellbeing
Counseling and Guidance support social-emotional wellbeing and safety for every student. A robust counseling program includes a dedicated social-emotional counselor in each division to provide preventive and supportive interventions. AISZ acknowledges rising anxiety and wellbeing concerns and addresses this through proactive counseling and support.

Safeguarding
AISZ maintains a Child Safeguarding Policy to protect students and families. Faculty and staff are mandated reporters, and safeguarding and duty of care procedures are described in policy. The school endorses the UN Convention on the Rights of the Child and views safeguarding as central to school life.
