If ISB determines a 1:1 teacher assistant is required to support a student's needs, the school will hire and supervise the assistant, invoicing the family for the additional fee (approximately 100,000 RMB for a full-time assistant per year). Generally, ISB believes students with learning disabilities and other challenges require specific and targeted instruction from a qualified special education teacher, rather than a teacher assistant. Teacher assistants may be employed at the discretion of the school.
