How do the GDO-R and the Gesell Screener differ?
Like the GDO ©2007, the GDO-R is an in-depth, multi-dimensional child assessment. Its purpose is to help educators, parents, and other professionals understand characteristics of child behavior in relation to typical growth patterns. The GDO-R is designed for use with 2½- to 9-year-olds and includes all original GDO ©2007 items with only a few minor edits. These changes include revised interview questions and the substitution of “mews” with “meows” in the Action Agent task. The GDO-R continues to provide a Developmental Age based on in-depth interpretation of the developmental items, just as before. The Gesell Screener is an early screener, based on selected GDO ©2007 items. It provides a quick look at the child and is intended for use with 3- to 6-year-olds. It has fewer items than the GDO-R, is scored objectively, and results in a simple, three-tiered scoring rubric.
