Assessment Tools

Gesell Institute offers resources for educators to help understand the ages and stages of child development, and how development relates to the individual learning needs of children in the classroom. 

The Gesell Early Screener (GES) is an instrument that can identify if a child may be at risk for developmental delay in one of four domains (Cognitive, Language, Motor, and Social/Emotional/Adaptive Skills).  Its more in-depth counterpart, the Gesell Developmental Observation-Revised (GDO-R), determines a child’s overall developmental age relative to chronological age.

The GDO-R requires participation in a training workshop, but the GES can be administered by users of varying levels of experience.  Both assessment instruments are complemented by the Teacher Questionnaire (TQ) and Parent/Guardian Questionnaire (PQ).
