Yes as steppemum says, all contact either by email or if telephone back tjis up with an email.
Email school to request meeting with member of senior leadership. Team or head explaining you have previously spoken to teacher to ask they be Seperate but this isn't working.
Try to jot down when you have requested this, any info eh was it by tel, at door of classroom when picking up etc, then go on to list the incidents that have happened, again, dates, details of incident, stress low level bullying that is not acceptable and you want to discuss. Don't let them focus on care pkan for your dd, focus has to be on pupils instigating these incidents - how are school promptly and efficiently dealing with them? Also ask if they use any system to record incidents, eg cpoms, so that as your dd moves through school there is a record of the relationship between your dd and this / other pupils.
It would be good that you keep a specific record of all incidents as, hopefully things will get sorted but if not, and you asked for a subject access request, school would have to provide all this info and it would be interesting to see what has happened at school and what school have officially recorded. (speaking with bitter hindsight!!)
