Early Childhood Environment Rating Scale®, Third Edition (ECERS-3)

The Third Edition of the ECERS is a major revision that introduces innovations in both the content and administration of the scale while retaining the continuity of the two principal characteristics of the ECERS, namely its comprehensive or global definition of quality and the reliance on observation as the primary source of information on which to base assessment of classroom quality.

The Scale consists of 35 items organized into 6 subscales:

  • Space and Furnishings
  • Personal Care Routines
  • Language and Literacy
  • Learning Activities
