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
- 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
