Measuring Change During Intervention Using Norm-Referenced, Standardized Measures: A Comparison of Raw Scores, Standard Scores, Age Equivalents, and Growth Scale Values From the Preschool Language Scales-Fifth Edition.

ABSTRACT:

Purpose

Norm-referenced, standardized measures are tools designed to characterize a child's abilities relative to their same-age peers, but they also have been used to measure changes in skills during intervention.
