Classroom Assessment Scoring System (CLASS)*
*CLASS is currently used as a coaching tool only. No CLASS assessment scores are averaged into star ratings at this time.
For Information about the CLASS tool please visit the Teachstone website.
General information and scoring for all Environment Rating Scales are part of the required training Introduction to Nevada’s Silver State Stars QRIS for center administrators. For more information on the ERS, please visit the ERS Institute website: http://www.ersi.info/
An overall ERS score for each center will be determined based on the scores averaged from 50% of each age group: infant-toddler (birth to 30 months) and preschool (2.5 to 5 years).
Star Level 3
Center has a minimum average ERS score of 3.50-3.99, with no classroom under 3.00.
Star Level 4

Star Level 5
Center has a minimum average ERS sore of 4.50-5.00, with no classroom score under 4.50.
An overall ERS score for each LEA will be determined based on the scores averaged from all state funded Pre K classrooms and 50% of co- located classrooms.
For LEA (district) Model scores see the LEA (District) Model
An overall ERS score for each Family Childcare center will be based on full program assessment.
For Family Child Care scores see the Family Childcare Model
Site Visit Protocol
- Once you have submitted your application to be assessed, an assessor will call you to schedule the assessment window
- Together you will determine the number and days of the site visits
- 50% of each age group will be randomly chosen for assessment. For this call, the assessor will need to know how many classrooms serve children mostly 2.5 years of age and younger (ITERS-3), and how many serve mostly children 2.5 years of age and older (ECERS-3)
- Let the staff know what to expect, when to expect it and how to proceed
- The assessor will arrive 15 minutes before the first observation for a brief center tour: layout of classrooms, outdoor areas, any group spaces, adult bathroom, etc.
- Assessor will randomly choose a classroom for observation that day and gather classroom information Information needed from the classroom:
• Birthdates of oldest and youngest child in that class
• Amount and type of disabilities currently served in that class
• Staffing patterns in that room throughout a typical day
• Start and end times in that classroom if different from posted center hours
- Assessor will immediately proceed to the classroom and begin observation
- Assessor will remain with children in that group for at least three and up to five hours, or until the assessor has gathered the needed information
- Assessor will not interact with staff or children and will try not to influence the activities or typical events in the classroom
- Assessor will be writing constantly
- Assessor will need to meet with lead teacher for about 20 minutes (usually during nap) following assessment
- No immediate feedback will be given on that day
