"The ECERS-R is a thorough revision of the widely used program quality assessment instrument, the Early Childhood Environment Rating Scale (ECERS). Designed for use in preschool, kindergarten, and child care classrooms serving children 2 1/2 through 5 years of age, the ECERS-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. "--BOOK JACKET.
