ERS-3 – Coming February 2023

Which tools are used?

Great Start to Quality uses three Environment Rating Scales (ERS), each designed for a different segment of the early childhood field.

ITERS-3 – Infant Toddler Environment Rating Scale

ECERS-3 – Early Childhood Environment Rating Scale

FCCERS-3 – Family Child Care Environment Rating Scale

How is ERS-3 used?

ERS-3 considers only what is observed during a 3 hour time sample to determine scores for Items that address the observed program, including activities, interactions, and language. ERS-3 On-Site Observations will be conducted by trained and reliable observers. This could be a Great Start to Quality Assessor or an Approved Assessor.

ERS-3 will also be used in the Self-Reflection as a Self-Assessment tool. Click here for more information on the Self-Reflection.

Who can use ERS-3?

ERS-3 can be used in any program type except schoolage classrooms and programs, which uses the SEL PQA.  Programs with Head Start and Great Start Readiness Program classrooms will only use CLASS for Great Start to Quality.

Threshold Scores

Programs must score a 5 or above for each group or classroom observation to reach Demonstrating Quality.

Observation Practice with ERS-3

Interested in having a practice ERS-3 observation conducted in your program? The Great Start to Quality Assessment Team will be conducting practice ERS-3 observations across the state in the fall of 2022 and would welcome the opportunity to practice in your setting.

All programs that have a practice ERS-3 will receive a feedback report to support their understanding of the tool. Scores from the practice observation will in no way affect a program’s current rating or future quality level.

If you are interested in a practice ERS-3 observation or have any questions about the assessment process please email,
