Winter/Spring ERS Professional Development Statewide Calendar

The Program Quality Assessment Team announces the statewide ERS session calendar for January through June of 2017.  This calendar is designed to support programs and teachers in selecting the most appropriate location and date to receive professional development on the ERS tools.  Additionally, if a session you are registered for is canceled for any reason, the calendar provides a quick at a glance way to find a new date and location to sign up for.  The calendar represents all currently scheduled sessions across the Commonwealth, but be sure to check the PD Registry for additional dates and locations as more sessions may be added.  

 ERS Statewide PD Calendar January-June 2017

Important Updates:

  • Policy Shift Impacts ERS Visits for STARS Providers
    An upcoming policy shift for ERS visits means that only sites that intend to move up a STAR level will schedule ERS visits so they can lock in their increased STAR level before next year. When the revised Keystone STARS program launches on July 1, 2017, currently designated programs will be able to maintain their 2016-17 STAR level through 2017-18. Effective February 1, 2017, OCDEL will prioritize scheduling of Environment Rating Scale (ERS) visits to programs moving to a higher STAR level before June 30, 2017. Asessors will be in touch to cancel the window and review information with programs.

    Due to prioritization, all types of STAR level maintenance ERS visits will be postponed until further notice, and will resume after the move-up ERS visits are complete. Current ERS scores will be extended for two years for programs renewing their STARS Designation. Programs with questions should contact their Regional Key. The Regional Key Specialist can help to identify high-quality goals for programs to maintain continuous quality improvement efforts.
  • A Strengths Based Approach to Best Practice Using the ECERS, Third Edition (ECERS-3) is now being scheduled at locations across the state.  Visit the Professional Development Registry to find a session near you and register today!

    The new ECERS-3 course is different than the other Environment Rating Scale Core Series sessions.  The information sheet below describes the new approach to thinking about quality practices and using the ERS tools.

The Environment Rating Scales (ERS) are observational assessment tools used to evaluate the quality of early childhood programs.  The ERS tools have been internationally tested for reliability and validity in providing information about the quality of childhood programs, based on current research regarding positive child outcomes.

There are five scales that are utilized in the PA Quality Initiatives: the Infant Toddler Environment Rating Scale - Revised (ITERS-R), the Early Childhood Rating Scale - Revised (ECERS-R), the Early Childhood Rating Scale Third Edition (ECERS-3), the School-Age Environment Rating Scale - Updated (SACERS-U), and the Family Child Care Environment Rating Scale - Revised (FCCERS-R). The tool utilized is dependent on the setting and age range of the children in a particular program.

Each ERS scale is divided into criteria that assess the program's physical environment, health and safety procedures, materials, interpersonal relationships, and opportunities for learning and development.

What is the process to have an ERS Visit at my facility?

How are the ERS tools used?

The ERS tools may be used by teachers, directors, technical assistance providers, and researchers.

Program staff may use the tools to complete a self-assessment of the quality of their classrooms, and to determine areas of high quality and areas that may need additional attention.  Technical assistance providers may use the tools to determine action plans for working with programs.  Researchers may use the tools to examine the quality of programs over time.

Why is an ERS assessment important?

When providers use the ERS scales to assess their own classrooms or have an outside assessor conduct assessments, they learn valuable information about strengths and areas of growth needed in each classroom and age group.  Using this information helps the providers make decisions about what areas of quality can be addressed in the early learning program.  ERS assessments also help Keystone STARS providers celebrate growth as they achieve the scores needed for STAR 3 and STAR 4 and make decisions about continuous quality improvement.

How do providers learn more about using the ERS tools?

In Pennsylvania, providers participating in Early Childhood Initiatives may access ERS professional development through the PD Registry.  The ERS Foundations course provides an overview of the structure and scoring of the ERS tools, and is a prerequisite for the tool-specific courses (ITERS-R, ECERS-R, ECERS-3, SACERS-U). Family and Group Childcare programs may access a combined course (FCCERS-R).

Determining the appropriate environment rating scale:

The charts below provide guidance for child care providers to use in determining which ERS trainings are most appropriate for their facility and which scale is appropriate for an individual classroom/group of children.

The following Department of Human Services Certification age-range definitions refer to typically developing children when applied to the use of the ERS Tools. In classrooms where at least half of the children are experiencing significant developmental delays, the developmental age of the majority of the children will determine the appropriate scale to use.


Infant Birth-12 months
Young Toddler 13-24 months
Older Toddler 25-36- months
Preschool 37 months to date child enters Kindergarten
Younger School-Age Kindergarten - 3rd grade
Older School-Age 4th grade through age 15

Determining the appropriate environment rating scale for Centers

To determine which scale should be used in center-based child care, programs should review the ages of the child in each group/classroom and find the corresponding scale for that group below. 


 Single Age CHILD Groupings ERS Scale to Use
 Young Toddlers
 Older Toddlers
 Preschool  ECERS-R/ECERS-3            
 Kindergarten  ECERS-R/ECERS-3
 Younger School-Aged
 Older School-Aged

 Mixed-Age CHILD Groupings  ERS Scale to Use
 Infants/Young Toddlers/Older Toddlers ITERS-R
 Older Toddlers/Preschool ITERS-R or ECERS-R/ECERS-3*  
 Preschool/Younger School-Age (Kindergarten Only) ECERS-R/ECERS-3 
 Preschool/Younger/Older School-Age ECERS-R/ECERS-3 or SACERS-U*
 Kindergarten/Younger/Older School-age

 *Mixed-age groupings comprised of these age-ranges will determine the most appropriate scale for the group by reviewing the group composition for number of enrolled children in each age-range (younger and older school age combined).  The age-range with the highest number of children enrolled will dictate the appropriate scale for use with the group.  In groupings where there is an equal distribution between the age-ranges the scale designed for the older group should be used, taking into account the emerging skills of the younger children in the group.  Programs that group school-age children with preschoolers should consult with their STARS Specialist to determine which scales will be used to assess their group for purposes of Keystone STARS, as in some instances both ECERS-R/ECERS-3 and SACERS-U will be used.    

Determining the appropriate environment rating scale for Family Child Care and Group Child Care Facilities

Family Child

The FCCERS-R will be used to assess all Family Child Care homes.

Group Child Care

The FCCERS-R will be used to assess all Group Child Care homes that are located in a residence. The chart below provides further information for Group Child Care homes that are located outside of a residence (e.g. in a church hall or store front): 

  Group Child Care In A Residence Group Child Care Out of Residence
Age groups separated by room (as in Center-based Care) FCCERS-R ITERS-R or
Age of the majority of the children enrolled will determine which training the provider should take and which scale will be used for assessment.
Settings Serving Only Children Kindergarten through Older School-age children in mixed grouping(s)             FCCERS-R SACERS-U
Settings Serving Only Children Kindergarten through Older School-age children in separate rooms        

Settings Serving Only Children Ages 3 years through Kindergarten
Settings Serving Children Ages Birth to 36 months Only   
Mixed Age Groupings include all ages of Children  FCCERS-R  FCCERS-R



The PA Position Statements are the result of the need to consider the impact of Pennsylvania Department of Human Services (DHS) Certification Regulations and other Pennsylvania program specific expectations on the scoring of the items in the Environment Rating Scales (ERS).  In the case of each statement input from multiple sources including the ERS Scale authors, DHS Certification, OCDEL and other experts were considered in the creation of the statements 

A Deeper Look at the PA Position Statements Tip Sheet

    Special Note:

    In October 2014, the PA Position Statements regarding sand were changed after discussion with input from the Bureau of Certification.  Based upon additional review, research, and input from stakeholders, the use of sand for children under 3 years old, either as a play medium or impact absorbing surface, is not prohibited. The PA Position Statement prohibiting the use of sand has been removed.

    Although the use of sand is permitted, there are factors that should be considered when using sand with young children, including supervision and abilities of the children. Certification will not cite sand when used as a protective surface for ground cover as well as a play medium. AAP/APHA guidelines for child care programs (Caring for our Children) recommend that when sand is used as a ground cover, it shall not be used simultaneously as a play medium for infants and toddlers.
