Yep, I just went into with the mindset that it wasn't a factor & they would decide if I could do the job or not regardless of the fact that I have a stutter. Honestly it doesn't matter if you choose to tell them at all. Just go with whatever makes you more comfortable. The most important thing you can do is to portray yourself as completely confident in yourself & your abilities. The way you present yourself is the single biggest factor in how people react to you in my opinion. It's all about perception. If you're visibly uncomfortable with yourself & display that you have no confidence, people will feed off of that & treat you that way as well. Don't look at this as an opportunity they're giving you. You're giving THEM a chance to utilize your talents. Trust me, you're probably a better candidate to teach people than you may believe. If you're anything like me, you're probably better at teaching than most others BECAUSE you stutter. Because words aren't always a strong point, I've found that I have a knack for finding creative ways to explain things that don't necessarily rely on verbal communication. This is especially important in teaching since there are so many different kinds of learners. You're in prime position to be able to get through to all of them & the institute would be doing themselves & their students a disservice by not hiring you. What makes you better than anyone else they can hire? These are the things you need to focus on. The fact that you stutter has no bearing on your ability to teach. If you believe that, everyone else will too.
