M-P-R

Features and benefits

• Assesses the five domains required by IDEA (cognitive, language, motor, self-help, and social-emotional).
• An Overall Developmental Index for all assessment scales related to intellectual functioning and additional measures of social-emotional functioning is also provided.
• Ideal for the assessment of general cognitive development in children, for the screening of infants and children who have been referred for the evaluation of possible developmental delays or disabilities, and for reevaluations of individuals previously identified as developmentally delayed.

Test structure

• Provides normative standard scores, percentiles, and age equivalence and criterion-referenced growth scores that are sensitive to change for the five IDEA domains.
• Features separate record forms for each domain and separate forms for the examiner and the parent within three of the domains.
• The Growth Score Profile allows the examiner to plot scores of individual IDEA domains, relating each to age equivalence.

Technical information

• Provides national normative data based on nearly 1,400 cases (more than 200 atypical) representative of U.S. Census statistics.
• Has excellent reliability. Internal consistency for the Developmental Index is .97–.98, with other developmental scales ranging from .87–.97.
• The Developmental Index correlates .92 with the Bayley Mental Scale, even higher with the Leiter-R, and .80–.86 with the Stanford-Binet Intelligence Scales, Fifth Edition (SB5) abbreviated battery.
