A few more details:

I am an assistant and listed my head director as a reference. I figured it would be a more informed reference as this person works closely with me everyday but if it seems strange maybe I should list my principal instead/also? I have several references from student teaching/college.

I am trying to leave a difficult situation that on its best day is simply a bad fit and on its worst makes me question every fiber of myself as an educator and person. I'm sure some of that is a normal adjustment to teaching but it's definitely time for me to move on. Since I am new to teaching, I've made a bunch of mistakes and I don't know if my admin will help me with a reference. None of the mistakes were absolutely heinous and I've taken responsibility for things with my admin, but there is still a general sentiment with the students, parents, and school community that I've done something "unforgiveable." The mistakes I am aware I have made I have taken action to resolve, but it also seems like I'm being judged on a metric that no one told me about. Like I said, I just want to move on and I know there will be plenty of celebration when I leave. If anything, my admin could give good references to get me out of their hair, but they could also leave my career dead in the water simply to be petty. I honestly don't know how common that is. I don't know how they feel about me. I don't know.

Last thing: My admin was pushing me to get my CDL before the end of the year. I began that process around the same time that I was thinking I might leave and now I am fully involved in the process, fully expecting to leave at the end of the school year. I know the CDL will make me more hirable, so I figured it would still be wise to complete it (with the bonus of pleasing my admin). Now I am nervous they'll stop and make me pay for the steps that I have already completed AND hold a grudge/give a bad reference.

Probably a bit too long but I just don't know what's going on or what to do.
