Recently, I became aware that my second student teacher preceptor gave a very bad phone reference. I was a little surprised because the written reference from last year (time of the student teaching) was below average but usable. Is it customary to mandate cooperative teacher references? Is there any way to not list it and use alternate references from one teacher that observed me, the other cooperative teacher, and the college teacher supervisor? What does HR do with cooperative teachers not listed as a reference. I assume I would have to list the cooperative teacher experiences and give contact information. Is there a way to designate who I want my references to be? Is it even possible to deny a request by a prospective employer to contact her for a reference? After some though, I decided that I am going to request, and I think the cooperative teacher would agree, to not respond to HR calls. The reference check person who I hired to check the reference relayed to me that he was only able to get a hold of her because he left a note at the main office, which the school delivered to her desk. She told him that, "she doesn't want to be a part of me." Alternatively, I could just say to prospective employers I can't get a hold of her and she never responded when asked to give a reference, she is in her late fifties and is planning to retire. Technically, I could also give her a cease and desist letter from a lawyer, which would limit her to giving title, and dates of employment (or training in this case). I have several interviews next week. I am new at this and have no idea what a district HR woman wants to do with a cooperative teacher I did not list as a reference. What say you? Please limit advice to the immediate problem of what to do based on impending interviews. Thank you for your support!
