Infant/Toddler Environment Rating Scale (ITERS-R): Revised Edition / Thelma Harms, Debby Cryer, Richard M. Clifford,

Designed for use in center-based child care programs for infants and toddlers up to 30 months of age, the Infant/Toddler Environment Rating Scale^®, ITERS–R, can be used by program directors for supervision and program improvement, by teaching staff for self‑assessment, by agency staff for monitoring, and in teacher training programs. The established reliability and validity of the scale make it particularly useful for research and program evaluation.

Featuring a spiral binding, the updated ITERS-R offers more practical assistance in the form of additional notes for clarification and an Expanded Scoresheet, which incorporates notes and tables to assist in scoring. However, the items and indicators remain the same as in the original ITERS–R.

Convenient organization in seven subscales:

• Space and Furnishings
• Personal Care Routines
• Listening and Talking
• Activities
• Interaction
• Program Structure
• Parents and Staff

Each of the 39 Items is expressed as a 7‑point scale with indicators for 1 (inadequate), 3 (minimal), 5 (good), and 7 (excellent). Notes for clarification and questions are included for selected Items.

An introductory section gives detailed information about the rationale of the ITERS–R, the process of revision, and the reliability and validity of the scale. Full instructions for administration and scoring, as well as a Scoresheet and Profile that may be photocopied, are included with the scale.
