Gesell Early Screener

Gesell Early Screener
The Gesell Early Screener (GES) assists parents, educators, and other professionals in quickly producing a snapshot of a 3 to 6 year old child’s development, compared to other children of the same age. This information helps to identify children who may be at risk for developmental or learning delays and might benefit from further diagnostic evaluation. It does not, however, assign a Developmental Age as its complementary assessment the GDO-R does.

Results of the GES are recorded as a Performance Level Rating across four domains of Development.

  • Performance Level Rating: A child’s abilities are defined as Age Appropriate, Emerging, or Concern
  • Domains of Development: Cognitive, Language, Motor, and Social-Emotional Developmental and Adaptive Skills.


While Gesell does not mandate any specialized training to use the GES (as is the case with the GDO-R) we do strongly recommend that users complete the GES online training. Importantly, Gesell recommends best practices for assessment of very young children when using the GES.
