The Gesell Developmental Observation-Revised (GDO-R) assessment system, updated with new technical data, strand scoring, and performance levels, also contains new materials that will make each administration more efficient and user-friendly.

The in-depth training is offered at sites across the nation for new, and experienced, users alike.  Three different workshops, and recertification workshops are available:

Training Options

Private GDO-R Group Workshops

Often schools and early childhood education centers prefer to hold a private group training, for their staff only. This could be as a team building PD exercise or because it is more cost efficient or because our currently scheduled dates do not match your needs. We would love to schedule a private GDO-R training with you.

The Private GDO-R Group Rate is $4,490 plus travel fees for the first 10 participants, and $395 for each additional participant over 10.

To schedule a Private GDO-R training for your group, please contact Erin Akers, National Director of Education and Development

Recertification Workshops – required every 5 years to maintain certification:

  • GDO-R Recertification Course for 2 ½-6 Year Olds $449.00 (3-days)
  • GDO-R Recertification Course for 6-9 Year Olds $149.00 (webinar only)
  • GDO-R Recertification Course for 2 ½-9 Year Olds $619.00 (3-days + webinar package)

In order to be eligible for Recertification, you must have completed a previous GDO-R training within the last 5 years. Due to evolving research and responsive adjustments to our curriculum, individuals trained more than 5 years prior to the date of their recertification must register as a beginner participant, and are not eligible for recertification discounts or programs.

Agenda of Workshops

Participants will be trained in the administration, scoring and analysis of the GDO-R to empirically discern developmental age and plan developmentally appropriately learning activities.

Gesell Developmental Observation-Revised (GDO-R) 2.5 – 6 Year Old workshops run from 8:30AM – 4:00PM.  Highlights from each day include a comprehensive overview of developmental age and its implications for learning; hands-on administration, scoring and analysis of the screener; and live demonstrations of the GDO-R on three differently-aged children.

Certificates of completion are provided for participants who attend all three days of the workshop.  Find out more about CEUs/Graduate Credit.
