The Infant/Toddler Environment Rating Scale (ITERS) measures the environmental quality of childcare programs for children up to 30 months old. The instrument was originally developed in 1990 and is now offered in a revised version (Infant/Toddler Environment Rating Scale-Revised, ITERS-R). The 39 items of ITERS-R focus on the following seven domains: space and furnishings, personal care routines, listening and talking, activities, interaction, program structure, and parents and staff. ITERS-R is suitable for inclusive and culturally diverse settings.
