Registration is Now Open for the IMC DERS & MEFS Consortium

The International Montessori Council (IMC) is pleased to announce an exciting opportunity to our member schools.

We are developing a consortium of schools in partnership with the National Center for Montessori in the Public Sector (NCMPS).

The consortium is open to ALL IMC member schools, including private, independent, public, and charter. We will be accepting 50 schools to participate, so it is imperative to get your questions answered and register your school right away! IMC Member Schools who agree to participate in this research-based project will benefit in a variety of ways.

First and foremost, this project will fuel your school’s efforts in continuous improvement. These assessment tools will provide information to schools and teachers that can be used to coach and mentor faculty, inform practice, and utilize support and resources to improve student outcomes.

Many of you have heard of the Developmental Environmental Rating Scale (DERS) and Minnesota Executive Function Scale (MEFS).

“The DERS is a classroom observation tool that measures environmental and behavioral qualities proven to support executive functions, linguistic and cultural fluency, and social-emotional development. Inspired by the specificity and coherence of Montessori learning environments, and developed over three years of school-based and laboratory research, the DERS provides a detailed, concrete, and dynamic view of what is happening inside classrooms for children between the ages of three and twelve.” —NCMPS

The MEFS provides a brief, reliable, valid, inexpensive, and easily administered direct behavioral measure of EF [Executive Function].

“The MEFS makes it possible to identify children in need of additional assessment, to track the development of EF [Executive Function] during childhood and beyond, and to evaluate the effects of interventions and curricula.” —Reflection Sciences

Below is a 90-minute IMC webcast about this program and four PDFs further explaining these tools and their validity.
