There is a preferred ratio of 1 teacher to 16 students, however fluctuations occur throughout the school year due to constant enrolments and transitions to mainstream schooling which may at times result in student numbers being lower or higher than 16 in a class.
The IEC has Ethnic Education Assistants (EEAs) who are multilingual and collectively speak approximately 16 languages as well as English. The EEAs assist the teachers in the teaching and learning program and as required, assist students and parents with interpreting.
In the event the EEAs are unable to speak a required language or are unavailable, the IEC will utilise external interpreting services.
