Hello. I'm applying for a teaching assistant post. I've been a SAHM since 2008, before this I was a teacher. The management team where I last taught has entirely changed and the new head/ deputy head etc have never worked with me. There are still teachers at the school who know me and there is a nursery nurse who I worked very closely with. Is it appropriate to ask this nursery nurse for a professional reference through the school or is the done thing to ask the head teacher and let them ask other staff members for input? Any other advice appreciated too!
