GDO & GES Assessment Workshops
The Gesell Assessment System uses direct observation, coupled with the unique perspective of parents and educators who know the child, to objectively examine a child’s cognitive, language, motor and social-emotional responses in five strands: Developmental, Letter/Numbers, Language/Comprehension, Visual/Spatial, and Social/Emotional/Adaptive.

Gesell offers two developmental assessments: the comprehensive Gesell Developmental–Revised (GDO-R) and the shorter Gesell Early Screener (GES). Certification is required for the GDO-R. Although certification is not required for the GES, a recommended self-paced GES training is available through our bookstore.
To meet a variety of learning modalities and preferences, public GDO-R workshops are held online throughout the year and on-site in New Haven at the historic Yale Child Study Center. Private workshops are also available in both online and in-person formats.
A Certificate of Completion is provided for all workshops.

The Gesell Developmental Observation-Revised Fundamentals: 2½-6-Year-Old Child
The Gesell Developmental Observation-Revised (GDO-R) is Gesell's hallmark tool and has since it's development it has been repeatedly validated and improved with the use of strand scoring and performance levels that allow for detailed evaluation in specific domains of growth.

Hybrid and Online workshop options available.
Please see calendar for dates and to register.
In this workshop participants will learn the fundamentals needed to administer and interpret the results of the Gesell Developmental Observation-Revised (GDO-R) as they relate to a child's neuro-motor, language, cognitive, social, emotional and adaptive responses. Our GDO-R Fundamentals course begins with all the tasks used with children 2½ to 6-year-old, and will all be applicable to those examiners wishing to further their assessment expertise with additional training needed to assess the 6 to 9-year-old child or to assess children virtually, using a web camera.
Specifically, this workshop will address these areas of knowledge and skill needed to responsibly utilize the GDO-R:
- Foundations of child development for children 2-6 years old
- Art and science of objective observation inspired by wonder
- How to administer and then interpret the results of the GDO-R for children 2-6 years old
Workshop Components
- In-depth study of developmental behaviors of the 2½ to 6-year-old child
- Comprehensive overview of developmental age and its implications for learning
- Demonstration of the administration of the GDO-R with the 2½ to 6-year-old child
- Hands-on practice of administration of tasks
- Training and practice on how to interpret and communicate the results of the GDO-R
Workshop Materials Included:
- GDO-R Examiner's Manual
- GDO-R Examiner's Script
- sample forms
Hybrid Workshop Requirements
- Pre workshop homework including a set of asynchronous online videos to review and online assignments to complete. These will be released for your review in the two weeks prior to the live in person meetings. It is essential to complete this work before attending the live meetings.
- Live in person workshop meeting dates (2.5 days)
- Online quiz to complete to demonstrate proficiency and understanding
- Post training homework including a set of asynchronous online videos to review and an online evaluation in the two weeks after the live meetings.
- Full attendance and submission of the above items is necessary to receive a certificate of completion.

Online Workshop Requirements
Spread out over a 4-week training period, there will be:
- 4 synchronous virtual meetings, each about 2 hours (see calendar) via Zoom
- A set of asynchronous online videos to review and assignments to complete. Courses are shared with participants weekly, one set at a time, corresponding with the discussion in the live meetings. As such, course work must be completed week-to-week so as to be sufficiently prepared for each live session. No material will be offered early, nor is it recommended to save all homework for the end of the training.
- Evaluations to complete in order to demonstrate sufficient proficiency to move forward to the next course, requiring an estimated 20-30 mins per week. Evaluations will be shared weekly, and no evaluations will be offered early, nor is it recommended to save all evaluations for the end of the training.
- Post training evaluation
- Attendance and submission of the above items is required to receive a certificate of completion.
- Optional: You are invited to submit a recorded assessment with accompanying child recording form, for review by an expert examiner, in the month after the end of the workshop

Gesell Early Screener (GES) Administration and Scoring Webinar
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. Unlike the GDO-R, no training is mandated to administer the GES. However, Gesell strongly encourages users to complete a new asynchronous online training to ensure reliability and validity in administration and scoring of the GES.

Feedback from our workshop participants
Excellent workshop. It is exciting to have a trainer who is so skilled and knowledgeable!
A very informative and useful workshop. I learned a lot about child development and feel comfortable applying what I've learned in a practical setting.
I love the information the Gesell Developmental Observation gives me about each student I have in my classroom! It helps me present learning and activities in a way best suited for each child's developmental stage.
Great training on a fascinating assessment. [Our trainer] was informative and kind about working with the novice assessor, and linked theory to practice. We were also offered plenty of time to experience the materials in a hands-on way. Thanks!
This was a great experience and I am eager to keep learning about the GDO-R. I will begin to start practicing!
[Our trainer] was PHENOMENAL! The way that she connected with each person and went out of her way to get to know us was delightful. Her perspective of the child and the way that she walked us through each step of the GDO-R was awesome.
