“I have had three graduates from MISD work at my campus in the past few years, and they have been fantastic!  The amount of knowledge and understanding of the theory and how to apply it to their classrooms is unsurpassed. I highly recommend MISD for its thorough and comprehensive training.
– Letty Rising, LePort Montessori School

Here at MISD, our mission is to train teachers in the Montessori method, an incredible philosophy of education originated by Dr. Maria Montessori over a century ago. Dr. Montessori believed that children are travelers on a limitless journey of self-creation, and that our role as educators is to gently guide them through this self-directed process.

But although the choice to learn, grow, and develop ultimately must originate with the child, setting up the circumstances in which this can best occur is a beautiful and complex art. At MISD, we teach you that art. We train knowledgeable, idealistic professionals, who are prepared in all ways to embark on a rewarding career in Montessori education.

You might enjoy our recently recorded webinar featuring a global panel of nine MISD graduates. Topics include:

  • What is it really like to work as a Montessori educator?
  • Tips for success in the job market
  • Advice for prospective AMI trainees
  • Public Montessori schools
  • Inclusive Education career paths
  • Employment abroad
  • Social justice

“It truly is an incredible gift to study here. The year I spent at the Montessori Institute of San Diego was one of the best of my life and I have no doubt it will be the same for all future generations of MISD trainees.” – Lauren, Primary class of 2012

"The graduates from MISD have been very keen on relating to the children, families and the staff. They are very thorough in helping the children as they track their progress. It has been a great experience to have these students on board."
