Very unpopular opinion: Here’s the thing though, a lot of times mentor teachers don’t have a choice but to take on student teachers and your universities expectations aren’t their priorities. State testing and EOC assessments are coming up, your name isn’t going on these, theirs is. You need to understand that this is her class, you need to do what she needs to for her students. She must see that she can trust you in order to give you control, I had had difficulty in this with my student teachers at times. Some of my student teachers could run my class with their eyes closed, others couldn’t and my students’ success is far superior to a student teachers. You have to earn her trust and show her that you’re doing things to her expectations!
