I have been offered a new job (maths teacher is SEN school). I put my current HOD and Head as references but my current school will only give one reference. This is my first school and I did my teacher training at the school so I can’t put my training mentor as the current school will only allow one reference! It’s years since I left uni so don’t want to put a tutor down. Can I put a former colleague as a reference? She wasn’t in a more senior position to me so I know it isn’t ideal, but I don’t know who else to go for.
