Why Accreditation Matters

So what does it mean that Three Tree Montessori is an AMI-accredited school?

We’re glad you asked. It can get a little confusing, because “Montessori” is not a trademarked term, so basically anybody can say they’re offering a Montessori education. While there are many unaccredited Montessori programs offering a superlative education, there are also programs with varying degrees of adherence to the rigorous training, principles, and practices established by Dr. Montessori. That’s where AMI, or the Association Montessori Internationale, comes in. Founded in 1929 by Dr. Montessori herself, AMI ensures that Montessori schools and guides world-wide adhere to the fundamental principles of the Montessori method, helping children attain their full potential in our society.

  • A trained Montessori guide with an undergraduate degree and a certificate from AMI’s year-long training program
  • A complete set of authorized Montessori materials
  • A three-year range of ages within each classroom
  • An uninterrupted three-hour work cycle each morning

Three Tree Montessori School is currently one of only a handful of schools in all of Washington with AMI accreditation, and we’re the only AMI accredited school for ages 1–12. You can read more about AMI and the accreditation process on the AMI/USA website.
