I would appreciate your advice. After graduating with an MAT, I took a replacement job that spanned four months. It was in a low-scoring high school. There were a few lapses by administrators. (I didn't get a working email password for two weeks. This made me not return email to a parent and I also missed an important dept. meeting. I did not get a key to my room when I started, and I was given no orientation or tour of the school. I also administered the PARCC without training. I chased down information/assistance from a few colleagues.) Still, I exhibited a positive, upbeat demeanor in spite of one of my classes having the following: one with ODD and Tourette's, who smiled as he interrupted the class with swearing, four left-back teens, and one with ODD who announced that she was going to kill me (also the Spanish teacher. My experienced SPED co-teacher grew to hate this class and even when we split it up, she stated that she was "just going to give them worksheets." I still designed LP's. I thought I had a good relationship with my mentor although she has not returned my email that asked her to confirm her contact info. While her letter of recommendation highlights my assets, it also states that I would become an effective teacher if under the supervision of a principal or mentor. In other words, while it touts my assets, it insinuates that I'm not up to snuff, right? When I had finished the job, I sent a letter to the principal who hired me, to thank him and certain colleagues - and to let him know that I'm now preparing slides and practices according to Wong and Lemov. I have no idea what he thinks of me and it is my fault that I had not asked when I departed. He had felt it necessary to visit this class to give them "a talking to" - to my chagrin. By the way,I have three superb letters from my student teaching experience. My question is this: do you think I should eliminate this replacement job off my resume/apps? Do administrators discover through searches - anyway - that you've had previous jobs?
