It’s Official: Full Accreditation for METTC 9-12 Program!

In July, MACTE (Montessori Accreditation Council For Teacher Education) awarded Full Accreditation status to METTC’s 9-12 standalone training program. This is one of only four AMS-affiliated programs in the country. All of METTC programs are now accredited by MACTE and approved by the American Montessori Society (AMS). METTC adult learners are assured of the broadest possible acceptance of their Montessori credentials

Montessori Elementary Teacher Training Collaborative (METTC)

Offering new teacher certification cohorts for Elementary I (6-9), Elementary II (9-12 including 9-12 stand-alone or 6-12 for those with 6-9 credentials), and Elementary I-II (6-12 over two or three summers) each Summer in Lexington, MA

METTC’s teacher education program carries the heritage of the highly respected CMTE/NY program that our experienced elementary faculty developed over 30 years. These veteran presenters formed the Montessori Elementary Teacher Training Collaborative and offered the Elementary I course for the first time in Massachusetts to 20 teachers during the summer of 2013, introduced the Elementary I-II course to 32 new teachers in 2014, and launched the 9-12 Elementary II course in 2015, with a 9-12 stand alone option in 2017. 2019 marked our seventh season of delivering high quality elementary Montessori teacher training in Lexington, Massachusetts.

METTC offers Montessori Elementary teacher training and certification programs for EI (6-9), EII (9-12), and EI-II (6-12). Adult learners join experienced faculty from across the USA and around the world for this unique training. For more information, visit
