Share your success
A: Getting an official letter is serious so you need to do all that your school requires of you, including deploying, leading and guiding the TA, which isn't easy, so ask advice from others. You are responsible for what she does in the classroom and if that means writing everything down, then do it. Try to understand your TA and get her on your side. What seems like laziness to you may really be a lack of confidence, not wanting to tread on your toes, or poor skills. Share the importance of success with your teaching assistant so that you work more as a team.
