GDO-R Materials

The Gesell Developmental Observation – Revised (GDO-R) is a comprehensive developmental screening tool that assists parents, educators, and other professionals in understanding characteristics of child behavior in relation to typical growth patterns.

Gesell assessments have been used as standard measures for child growth and development since the introduction of the initial scales in 1925. Long used by pediatricians and currently under a national normative and exploratory research study, the GDO focuses on direct observation to measure a child’s neuro-motor, language, and cognitive development. The comprehensive GDO-R is designed for use with children from 2-1/2 to 9 years of age.

The GDO-R assessment kit may be purchased as a complete set in a durable tote bag. Please see pages 7-8 in our catalog for pricing and order information, or place your order on-line here.
