what our aim alumni have to say

"I mean, how cool is it that you not only get these manuals describing each step of what each lesson entails, but you're able to watch and experience spot as a teacher, go through each step of those lessons and you can watch it as many times as you need.

You can look at that video and it's going to give you the confidence you need to go in there and just nail it. I love the video library. It's amazing."

"What I love about aim is that you're getting a super comprehensive understanding of the philosophy and teachings of Maria Montessori, and then you're going into the classroom and you are figuring out how to do it yourself, and you are getting the tools both through faculty observation and mentoring, how to really make it your own. I loved the in-depth understanding that I received in the academic program."

"The online course was so thorough and thoughtfully done that I knew during the course that I was going to be very well prepared and good at what I was doing. As somebody who is very invested in what it means to be a teacher, not just to deliver content, but to affect a child's life, the online course created space for me to explore and refine those parts of myself in preparation to be a better guide for the children in my care."
