Gesell Early Screener

What is the 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. The GES can be administered to a child by persons with varying levels of experience in less than 20 minutes. 


The components of the GES include:
• GES Examiner’s Manual: all instructions needed to administer the GES
• GES Child Recording Form (CRF-S): standardized sheet to track observations
• Sanctioned Gesell Manipulatives: official materials needed to administer the GES with validity
Teacher Questionnaire and Parent/Guardian Questionnaire (electronic)
GES Strand Scoring Worksheet : auto-calculating worksheet to tally results

 Purchase all GES materials here.


The Results of the GES 

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.

Unlike the Gesell Developmental Observation-Revised (GDO-R) the GES does not assign a Developmental Age. To better understand this and other differences between the GDO-R and the GES, to assist you in making an informed decision, we suggest viewing this short video.


Training to Become a GES Examiner

No training is mandated to administer the GES (unlike the GDO-R). A manual is included in your GES kit purchase and can be followed by individuals with experience using the GDO-R as well as by some child development or education professionals.

However, Gesell strongly recommends that to be best prepared, GES examiners:

    1. Complete a brief online workshop to ensure they are adequately trained in valid administration and competent in analyzing results. View workshop details here.
    2. Complete a Foundations of Child Development recorded webinar. View workshop details here
    3. Adhere to assessment best practice, as summarized here.

Group Workshops: Live virtual training is available for school groups interested in being further supported in the art of administration and science of analysis of the GES.
