Merrill-Palmer – Revised Scales of Development Gale H. Roid, Ph. D. and Jackie L. Sampers, Ph. D.
Age Range: 1 month 6 1/2 years
Time: Approximately 45 minutes administration
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).
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
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
Addresses Five Major Assessment Needs
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
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 Growth Score Profile allows the examiner to plot scores of individual Developmental Index domains, relating them to Age Equivalence, and across Developmental domains. Once these scores are plotted, specific areas of deficit can be identified using test item performance, relative to expectations. These results can then be used to develop an educational plan targeting those deficits.
Ordering InformationThe 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.
The complete Merrill-Palmer-R includes the comprehensive Administration/Scoring Manual, Infant Stimuli book, Easel Book, Fido Book, Choke-Safe Toys and Manipulatives, and 20 each of all necessary Forms (English only) in a convenient Rolling Bag. All forms are sold in packs of 20.
