Linking learning environments
to meaningful outcomes
Record observations, view trends and track progress over the course of the school year.
Inspired by child-centered Montessori learning environments,
the DERS helps teachers and schools support children's natural development.
The DERS measures qualities such as patience and persistence in children, precision and clarity in lessons, and order in the environment, which support the development of executive functions, literacy, and social-emotional learning.
Trained observers use the DERS iPad app to rate 60 research-based environmental attributes over a one hour observation. Printed or emailed reports can be used as an assessment of environmental quality and a tool for continuous improvement.
