For this question, make sure your answer is honest and relatable, but not too negative. This is one of the few questions where you don’t want to elaborate too much, as you could risk coming off as complaining. A good framework to follow for this question is to share your least favorite part about teaching, explain why you dislike it, acknowledge that it needs to be done, and share how you find motivation for doing it.
For example, perhaps your least favorite part of teaching is the amount of standardized testing. In that case, your answer may sound something like this:
“My least favorite part of teaching is the amount of standardized testing that is used, because I know it only gives a snapshot of a student’s abilities. I know that standardized tests are necessary to make sure all students are getting a quality education, and I know they can provide important data for teachers to use. However, I always make sure that I’m using additional assessment measures so that I can get a full picture of my students’ knowledge and abilities.”
