Suppose a question like this arises during your interview. In that case, there is no need to fret as your interviewer is simply looking to hear your passion for working with the technology designed for a specific age or grade level. There is no right or wrong answer. If the position you are interviewing for will focus on a particular age or grade range, that will be spelled out in the job posting details. If that is the case, be sure to talk about your preference for that group of learners. If this position spans over an entire district, then feel free to speak openly and honestly about where you do your best work and describe why.
