Description

The Merrill-Palmer-Revised Scales of Development (M-P-R; Roid & Sampers, 2004) assesses cognitive, social-emotional, self-help, and fine and gross motor development in infants and children under the age of 6 years, 6 months. It is an individually administered, norm-referenced measure.

The M-P-R consists of four discrete assessment batteries. Parent reports are given in the areas of Expressive Language, Social-Emotional Development, Social-Emotional Temperament, and Self-Help/Adaptive. Clinician administered scales include Cognitive, Gross-Motor, and Expressive Language.

The Cognitive Battery measures general cognitive, receptive language, and fine-motor areas. It also provides supplemental scores for memory, speed of cognition, and visual-motor ability. The Gross-Motor Scale consists of general gross-motor development, unusual movements, and atypical movement patterns. The test results can be used to monitor premature infants; identify developmental delays; track improvements; evaluate children with hearing impairments, autism, or limited language skills.

Why use M-P-R?

  • Early identification of developmental delays
  • Change-sensitive assessment of premature infants
  • Measurement of incremental improvement in development
  • Reliable and valid developmental assessment for children with limited expressive language ability
  • The comprehensive assessment required by IDEA, to develop Individual Family Service Plans (IFSP) and Individual Education Plans (IEP)

Who can administer Leiter-3?

  • Graduate-level training in intellectual assessment
  • Psychologists
  • Occupational therapists
  • Educational diagnosticians
  • Speech and language pathologists
*Final Scoring And Interpretation Would Best Be Conducted By Experienced Psychologists Who Adhere To Ethical Standards.

M-P-R assessment use

  • Assess children for general development.
  • Assess infants and children for possible developmental delays or disabilities.
  • Assess children with hard-of-hearing conditions, autism or other cases of limited expressive language.
  • Re-evaluations of individuals previously identified as developmentally delayed.
  • Preschool assessments in research projects, dissertations and theses.
  • Other uses requiring a nationally-standardized measure of child development
