ERS & Verification

Environment Rating Scale Assessment

The Environment Rating Scales (ERS) are observational tools used to assess the quality of early care and education programs including those that serve infants, toddlers, preschoolers, and/or school age children. The Infant-Toddler Environment Rating Scale- Revised (ITERS-R) is used to assess classrooms serving children 6 weeks to 30 months. The Early Childhood Environment Rating Scale- Revised (ECERS-R) is used to assess classrooms serving children 30 months through 5 years. The School Age Care Environment Rating Scale (SACERS) is used to assess school-age only programs. The Family Child Care Environment Rating Scale-Revised (FCCERS-R) is used to assess family child care and large family child care programs.


Verification refers to the process of verifying a program’s supporting documentation for all standards required and chosen in order to determine if the program meets the minimum requirements for the desired Star Level.  For Star Levels 3 through 5, verification is a two-step process.  Programs must have ERS assessments as the observational portion of verification.  Additionally,  they must verify with the Delaware Stars Standards for their program type.  A verification visit is conducted to review the evidence and documentation of the program standards with points being accumulated to designate the Star Level earned by the program.

Programs must re-verify Star Levels 3 through 5 every three years.  There are Program Change guidelines that may require re-verification sooner.  In addition, programs that go on enforcement action by the Office of Child Care Licensing must re-verify their Star Level Designation once they are off enforcement.

For information about Alternative Pathways to Star Level Designation, including information for National Association for the Education of Young Children (NAEYC) POLICY NAEYC pathway, Head Start POLICY Head Start Pathway and public school 619 Pre-K programs POLICY Public Schools select the appropriate policy.
