The Environment Rating Scales (ERS) are the most commonly used observational tools for center-based ECE. Three quarters (75%) of states using the ERS for some purpose, whether for the rating itself or for quality improvement. The Classroom Assessment Scoring System is the second most commonly used tool. Just over half (55%) of states use the CLASS tool.

As with Child Care Centers using the ERS, the most commonly used tool for home-based ECE is the FCCERS-R, used by 77% (n=33) of QRIS. After the ERS, the CLASS is second most often-used, by 14% (n=6) of QRIS.
