The interviewer wants to decipher not only whether or not you are self-aware enough to know of your weakness, but also how you are actively combatting that weakness in order to improve. Share a weakness that does not impact your ability to do your job well and how you are taking steps to improve in that area.

"A weakness of mine is long-term planning. I get so excited about what I teach, and I have so much to say, that I often get distracted by projects and questions that come up in class. I'd like some support planning out my units within the broader school year so that it makes the most sense to students. I have already been working on adjusting a few things and hope to meet with an instructional coach or colleague for advice in the near future."
