For Early Years, the Nursery has a maximum of 15 students, with PreK1 to Kindergarten capped at 20 students. Our teaching model is unique with every early-years classroom consisting of an Early Education Teacher and an Early Education Teacher Fellow. The Early Education Teacher is an expatriate teacher who typically has broad experience in teaching early-years or has a degree in early education. Their role is to bring the BASIS curriculum to life in the classroom and are experts in the pedagogy of early-years education. The Early Education Teaching Fellow has a similar background to the Early Education Teacher, but are native Thais. Their role is to co-teach with the Early Education Teacher and help to accelerate the English language acquisition of our non-native English-speaking students. Nursery, PreK1 and PreK2 also have Nannies to assist our two teachers in the classroom.
For the Primary, Grade 1 through Grade 5 the maximum capacity is 25 students per class. With these grade levels, our students have a Learning Expert Teacher (LET) that stays with them throughout the day and an individual Subject Expert Teacher (SET) that joins their class for each subject. In the case of Grade 5, we have an Academic Coach who is responsible for the whole grade level.
For Middle and High School, the maximum capacity is 25 students per class. Grade 6 and above will also have up to 25 students but have an individual Subject Expert Teacher for each subject.
