Evidence of Qualifications and Teaching Experience and Reclassification. (a) On or before engagement, a school may require a teacher to provide documentary evidence of qualifications and teaching experience. If the school considers that the teacher has not provided satisfactory evidence, and advises the teacher in writing to this effect, then the school may decline to recognise the relevant qualification or experience until such evidence is provided. However, a school will not unreasonably refuse to recognise the qualifications or teaching experience of a teacher. If it becomes apparent that a teacher has been wrongly classified, the teacher's classification will be changed to reflect the appropriate classification according to the teacher’s qualifications and teaching experience.
