I have been invited to interviews after teaching in an international school. Two of the schools I have applied at are stating that my referees and experience abroad are not relevant to the teaching post I have applied for. Therefore they are contacting a school I left 6 years ago for a reference and more information. When I asked them about pay, they said they would start me on M3, even though I now have 6 years teaching experience. The school I taught in followed the British Curriculum for KS3, then IGCSE and IBDP. Is this normal?
