It is a requirement that the recommendation is provided by the principal (or their delegate) or panel chair at the school/service where most of the teaching practice has been undertaken and documented. 

Before endorsing an application for full registration, a school/service must have observed the teacher’s practice over an extended period. The recommendation must be based on a consistent representation of practice over time and the principal (or delegate) or panel chair must be satisfied the teacher has provided sufficient evidence that the Australian Professional Standards for Teachers (APST) have been met.
