Description by National Centre for Montessori in the Public Sector, Inc. Written by the developer, not by AppBrain. Click to read.
The DERS consists of 60 research-based environmental attributes or observable behaviors (child and adult) aligned with five broad aspects of human development: initiation and concentration, inhibitory control, working memory, linguistic and cultural fluency, and social fluency and emotional flexibility. The assessment is administered in a 60-minute classroom observation, during which the assessor records the presence, magnitude, and/or frequency for each item. Schools can use the DERS internally to identify priorities for continuous improvement or externally as an assessment of environmental quality.
The DERS was developed by researchers at the National Center for Montessori in the Public Sector.
