There are four Environment Rating Scales (ERS), each designed for a different segment of the early childhood field:
- Early Childhood Environment Rating Scale (ECERS)
- Family Child Care Environment Rating Scale (FCCERS)
- Infant/Toddler Environment Rating Scale (ITERS)
- School-Age Care Environment Rating Scale (SACERS)
The scales have proven reliability and validity and are suitable for evaluating inclusive and culturally diverse programs. Each one of the scales has items to evaluate, including physical environment, basic care, curriculum, interaction, schedule and program structure, and provisions for parents and staff.
