Getting Started with Your School Accreditation

To get started with AMS school accreditation, the first thing you’ll need to do is review our eligibility requirements. If you believe you meet them, there are a few basic steps to take next, which we outline lower down on this page.


If your school meets all of the following requirements, you are eligible to apply for AMS accreditation:

  • It has reached Step 6 on the AMS Pathway of Continuous School Improvement, a quality assurance initiative available to all member schools
  • It has been in operation for at least 3 years
  • You are seeking accreditation for all the program levels offered by your school
  • It is structured and staffed according to the following multi-age groupings:
    • Infant, within the range birth – 18 months
    • Toddler, within the range 15 – 36 months
    • Early Childhood, a 3-year grouping within the range 2.5 – 6
    • Lower Elementary, ages 6 – 9
    • Upper Elementary, ages 9 – 12 or Elementary I – II, ages 6 – 12
    • Secondary, either 12 – 14, 14 – 16, 16 – 18; or 12 – 15, 15 – 18
  • All lead teachers hold Montessori teaching credentials for the ages they are teaching (in accordance with Standard 5.2 of the AMS Standards for Accreditation)
  • All lead teachers who do not hold the requisite Montessori credential are enrolled in an AMS-, AMI-, or MACTE-accredited Montessori teacher education program and are actively working toward earning a Montessori credential for the level at which they teach. Self-directed adult learners may serve in lead teaching positions in AMS-accredited schools and candidate schools.
  • Has a minimum of a half-day session taught by a qualifying Montessori-credentialed teacher if your school offers in all Infant & Toddler and/or Early Childhood levels
  • At the time of application, it is in at least 80% compliance with all AMS Standards for Accreditation.
