Infant/Toddler Environment Rating Scale®, Third Edition (ITERS-3)
The Third Edition of the ITERS is a major revision that introduces innovations in both the content and the administration of the scale, while still retaining continuity of the two primary characteristics of the ITERS—its global definition of quality and its reliance on observation as the primary source of information on which to base assessment of classroom quality.
Scale consists of 33 items organized into 6 subscales:
- Overview of the Subscales and Items
- Reliability and Validity
- Additional Notes
- Supplementary Materials
