Question: What is the Merrill-Palmer-Revised? Answer: The Merrill-Palmer-Revised Meets the needs of infant and early childhood assessment, required by federal legislation and most states for early identification of developmental delays and learning difficulties. The MPR is designed for ages 1 month - 6 1/2 years and the test takes approximately 45 minutes to complete.
The latest revision of the 1931 Merrill-Palmer Scales, the Merrill-Palmer-R retains the types of engaging hands-on activities that hold the interest of even the youngest subjects. Innovative, toy-based activities assess visual-motor, learning and problem solving using choke-safe, colorful materials. In the tradition of the Leiter-R, Stoelting has completely updated, revised and expanded the well-known and well-respected Merrill-Palmer Scales of Development. The Merrill-Palmer-R follows the natural progression of activities for children from 1 month to 6-1/2 years, and is especially useful in assessing children born pre-term (premature).
The Merrill-Palmer-Revised Provides global assessment with separate scores for each IDEA Domain
Cognitive
Language/Communication
Motor (fine and gross)
Social-Emotional Development
Self-Help/Adaptive and more
The Merrill-Palmer-Revised Meets the Requirements of IDEA Legislation
The Merrill-Palmer-R provides normative standard scores, percentiles, age equivalents and criterion-referenced, change-sensitive growth scores for the five IDEA domains:
Cognitive Development: Verbal and Nonverbal Reasoning, Memory, Visual Motor and Speed of Processing
Language/Communication Development: Receptive and Expressive Language, evaluated by Examiner and Parent
Motor Development: Fine Motor and Gross Motor
Social-Emotion Behavior: Developmental Scale and Clinical Data, rated by Examiner and Parent
Self-Help/Adaptive Behavior: Developmental and Global Examiner and Parent Rating Scales
The Merrill-Palmer-R Addresses Five Major Assessment Needs
1. Early identification of developmental delays
2. Change-sensitive assessment of premature infants
3. Measurement of incremental improvement in development
4. Reliable and valid developmental assessment for children with limited expressive language ability
5. Comprehensive assessment required by IDEA, to develop Individual Family Service Plans (IFSP) and Individual Education Plans (IEP)
Recommended uses for the Merrill-Palmer-R
Developmental assessment of Cognitive, Language/Communication, Motor, Self-Help and Social-Emotional Domains, required by federal and state regulations
Assessment of general cognitive development in English- and Spanish-speaking children
Screening of infants and children who have been referred for the evaluation of possible developmental delays or disabilities
Assessment of children with hearing impairments/deafness, autism or other disabilities with limited language skills
Re-evaluations of individuals previously identified as "developmentally delayed"
The Merrill-Palmer-R has excellent reliability. Internal consistency for the Developmental Index is .97-.98, with other developmental scales, ranging from .87-.97. Scale information curves are provided. Validity data includes extensive content-related, criterion related and consequential validity studies. The test is a good fit to the Rasch Model, and expert evaluations supported the content structure. The Developmental Index correlates .92 with the Bayley Mental Scale, even higher with the Leiter-R, and .80-.86 with the SB-5 abbreviated battery.
The Manual provides national norms based on nearly 1,400 cases (over 200 atypical), corresponding to the 2000 Census for gender, ethnicity, socioeconomic level and geographic region.
