Assessment Tools

Gesell Institute of Child Development offers resources for educators to help understand the ages and stages of child development, and how it relates to the individual learning needs of your child in a classroom setting.

GDO-R

The Gesell Developmental Observation-Revised (GDO-R) is a comprehensive, multi-dimensional assessment system that assists educators and other professionals in understanding characteristics of child behavior in relation to typical growth patterns between 2½ to 9 years of age. It uses direct observation to evaluate a child’s cognitive, language, motor and social-emotional responses. Your child’s performance will correspond to a Performance Level Rating (Age Appropriate, Emerging or Concern) and the GDO-R will result in a Developmental Age.

The results of the GDO-R provide information to both parents and teachers regarding a child’s educational needs. This shared information portrays the child’s strengths as well as areas that may need additional support. The results provide a teacher with a greater understanding of the child’s Developmental Age which then provides direction for differentiated instruction.

 

GES

The Gesell Early Screener (GES) is a quick screening instrument that can “flag” any child who may benefit from further diagnostic evaluation. It can identify if a child may be at risk for any developmental delay. It does not, however, assign a Developmental Age, as its complementary assessment, the GDO-R, does.

Tools

The Teacher Questionnaire (TQ) and Parent/Guardian Questionnaire (PQ) complement both the new Gesell GDO-R system and the GES by providing valuable insight from the individuals who know the growing child best. Parents and educators can now work together to understand appropriate expectations to meet the individual needs of each child.
