The Preschool Evaluation Scale-Second Edition (PES-2) was developed to provide educators, diagnosticians, pediatricians, and psychologists with a measure of child development from 0 through 72 months of age. The PES-2 may be used to contribute to the early identification of students with developmental delays for the purpose of implementing an intervention plan for remediation. The PES-2 is based on the most commonly recognized domains of child development identified in the federal definition of developmental delays (PL 99-457). Each subscale is associated with one of the developmental domains: Large Muscle Skills, Small Muscle Skills, Cognitive Thinking, Expressive Language Skills, Social/Emotional, and Self-Help Skills.
Internal consistency, test-retest, and inter-rater reliability; item analysis; and content, criterion-related, diagnostic, and construct validity are documented and reported for the scale.
The PES-2 is completed by a child-care professional in the child’s home or while other screening activities are taking place. The PES-2 can be completed without requiring additional time on the part of screening or diagnostic personnel. For early and efficiently gained developmental information, the PES-2 is a must for all preschool screening. Converting raw scores to standard scores is a clerical activity and involves no more than a few minutes per subscale.

Characteristics and Components of the PES-2

• The PES-2 is based on the federal definition of developmental delays (PL 99-457).
• The PES-2 School Version was standardized on a total of 1,608 children.
• The PES Home Version was standardized on a total of 979 children.
• The PES-2 SV standardization population included children from 22 states and represented all geographic regions of the United States.

 

• The PES-2 HV standardization population included children from 18 states and represented all geographic regions of the United States.
• The PES-2 School and Home Versions provides separate norms for male and female children 0-35 months of age and 36-72 months of age.
  
  
• The PES-2: 0-35 Months School and Home Versions can be completed in approximately 20 minutes and include 94 items easily observed and documented by educational personnel and parents/guardians.
  
  
• The PES-2: 36-72 Months School and Home Versions can be completed in approximately 20 minutes and include 85 items easily observed and documented by educational personnel and parents/guardians.
  
  
• The Preschool Developmental Guide includes IEP goals, objectives, and interventions for all 94 items on the PES-2: 0-35 Months rating form and all 85 items on the 36-72 Months rating form.
  
  
• The PES-2 Quick Score computer program converts raw scores to standard and percentile scores and makes the scoring of both the School and Home Version rating forms efficient and convenient.
