I am hoping to get a job teaching H.S. Chemistry this next school year and I am working on updating applications and my resume. I am a hopeful career changer and have not been in a classroom setting in 10 years (which was during student teaching). A friend and I were having a discussion about this potential change and I asked her opinion about reference letters. She says yes, they need to be there. I feel like since these letters are over 10 years old and one of the CT has retired (several years ago), they do not need to be included. What does everyone else think? Thanks for the input!
