The Mission Statement of Gesell Institute is to promote the principles of child development as the basis for all decision making for young children.
The Institute’s namesake, Arnold Gesell, Ph.D., MD, began his groundbreaking work in the early 20th century. He developed a set of norms illustrating sequential and predictable patterns of growth and development, which were used as the basis of the original Gesell Developmental Observation. Dr. Gesell was the first Director of the Yale University Clinic, now known as the Yale Child Study Center, as well as becoming the nation’s first school psychologist. He was the founding member of the National Association for Nursing and Education, which is now known today as the National Association for the Education of Young Children (NAEYC).

Following Dr. Gesell’s retirement from Yale in 1950, his colleagues opened Gesell Institute in New Haven, Connecticut to continue his life’s work. Since that time, the Institute has offered a variety of medical and educational programs and services to promote the healthy development of children worldwide. Today, the work of the Institute is focused on educating and supporting teachers and parents in order to ensure the future success of all children throughout the United  States and abroad.

Gesell Institute of Child Development is now an independent non-profit organization located directly on Yale University’s campus in New Haven, Connecticut. It has been associated with understanding how children grow and learn since 1950. Gesell programs and publications help parents and educators understand the ages and stages of childhood.

Understanding the stages of child growth and development, and then using this knowledge to interpret behaviors, to plan appropriate curricula, and to manage the classroom are essential to quality teaching practices. Gesell professional development workshops, seminars and webinars link the continuum of growth to the use of an effective screening tool, the Gesell Developmental Observation – Revised ©2011 and the new Gesell Early Screener ©2011.

Our mission is to promote the principles of child development as the basis for all decision making for young children.

Gesell Institute provides multiple sources of information for parents, teachers, and schools to assist them in making important decisions about children. We do not set policy or provide recommendations surrounding issues of retention, placement, or readiness “scores” in association with the Gesell Developmental Observation –Revised.

Support the updating and creation of content and provide the technology needed to deliver a set of parent education webinars, patterned on the long standing Gesell Institute of Child Development book series “Your One Year Old” “Your Two Year Old” through “Your Seven Year Old”.

CEO Statement
After nearly seven decades, we’ve seen many fads and trends in education come and go. Through them all, the Gesell Institute of Child Development has stuck to one powerful mission: helping parents and teachers to understand child development better. The drawback of all that experience is that it is tempting to think we’ve seen it all. For organizations like ours that were part of introducing the very idea of preschool, the challenge is to hold onto a sense of wonder. It is from this perspective that we now approach our training of teachers and parents. Our work, like yours, is to cultivate awe and appreciation for the development of young children, even when caregivers and teachers feel as though they’ve seen it all. This year we’ve revisited our trusted Gesell Developmental Observation training and infused it with sparks of new research, new interactive learning exercises and new ways of using the results to better support children’s development. By bringing new eyes to our time tested techniques, our trainings are transformed. So, even after over 65 years of observing children, our focus is still on experimenting and innovating. As Arnold Gesell once said, “Every generation rediscovers and re-evaluates the meaning of infancy and childhood.” Stay with us in 2018, as we continue to rediscover the meaning of childhood for today’s children.


Board Chair Statement Gesell’s commitment to developmentally appropriate early childhood education, professional development for educators, and advocacy for positive child development continues to guide our work. This past year, under the leadership of Peg Oliveira, Gesell has implemented strategic plans to streamline administration, revamp procedures, update existing materials and create new resources, to provide meaningful professional learning opportunities to educators across the nation. Gesell staff have provided classroom child assessment and technical assistance with programs across Connecticut. Dr. Oliveira continues to represent Gesell at local, state and national conferences. Both Peg and Erin Akers, Director of Education and Development, have had articles printed in the Southeastern Education Network Magazine. Dr. Oliveira was an invited speaker to provide commentary at the Association for Childhood Education International’s (ACEI) 125th anniversary. I invite you to read more about our accomplishments and visit our newly designed website where you will find information on the many resources Gesell has to offer. Please join me in supporting Gesell and consider a donation to support our important work.

CEO/Executive Director/Board Comments


Gesell Institute offers workshop training on how to properly administer our Gesell Developmental Observation-Revised ©2011 assessment tool, which can be used with children ages 2 ½ to 9. Our workshops are hosted by schools and child care centers all across the country. A Gesell representative from our National Lecture Staff (NLS) travels to the location and hosts the 3-day workshop. Gesell Institute pays for the NLS’s travel and housing expenses.

Short Term SuccessHelpOrganizations describe near term achievement(s) or improvement(s) that will result from this program. This may represent immediate outcomes occurring as a result of the end of a session or service.

We have programs and products that help teachers and parents understand their child’s development which can contribute to a smoother transition when starting school and deciding what is and is not appropriate curriculum.   If schools, public and/or private would learn the information we have to offer, and use our assessment tool, the GDO-R, they would have a more solid understanding of the children in their classrooms and be in a better position to navigate the chasm that often exists between the expectations and curriculum of a particular grade and the abilities and readiness of the actual children who are expected to master the information. 

Long Term SuccessHelpOrganizations describe the ultimate change(s) that will result from this program. This may be far into the future and represent an ideal state.

Gesell Institute's Director of the National Lecture Staff is Sally Keller. She says: the ideal “ultimate” change would be that the curriculum would reflect a child’s readiness to learn and not an arbitrary skill or task someone who does not know how children grow and learn expects children to master. For example all the research on learning letters and pre-reading reveals that 4 ½ to 5 year olds (the age many children enter Kindergarten) recognize only 10 to 12 letters however the curriculum for most all Kindergartens expects that entering Kindergarteners know all their letters and even their sounds.  This huge disconnect between application and research/best practices causes many of the problems in schools today. My ideal state would be that the curriculum would be a better match to the developmental levels of the students in that grade. I would expect that referrals for reading support would decrease, retention rates would decrease, as would referrals for Special Needs evaluations.

Program Success Monitored ByHelpOrganizations describe the tools used to measure or track program impact.

We will know what is and is not working by whether or not we have established an ongoing relationship with schools. Another way to assess our effectiveness is thru the evaluations we give at the end of our 3 day GDO-R workshops. On the last afternoon of the 3 day GDO-R workshops we pass out an evaluation form which asks questions about the presenter, the material, and the Institute. Evaluations are made regarding relevance, communication, and presentation. These evaluations are used to improve communication or product, and/or to assess the person presenting the information. We also have a facebook page which tracks “hits” and interest as well. 


Examples of Program SuccessHelpOrganization's site specific examples of changes in clients' behaviors or testimonies of client's changes to demonstrate program success.

As with many organizations there are times of much activity and times of less activity. Because we have invested many of our resources in updating our product(s), we are looking forward to an increase in demand. Our current materials are being very well received as evidenced by comments on our evaluations over the summer workshops. Our information is timeless and always applicable however updating to reflect current education concerns and issues is essential. Many schools could not use our product because we could not show a current “renorming” or data collection. Now that it has been completed, we are positioned to move into many areas that we did not have access to previously. Evaluations included comments like : “I can’t believe I ever taught 1stgrade without this knowledge! I am so much more equipped to understand my students than I was. This will change how I teach,” and “Understanding the Ages and Stages of development has totally changed how I teach and parent. I did not understand how knowledge grew in; I just thought I hadn’t taught it yet! Now I know how the whole child grows!”

Description Gesell offers high quality and relevant webinars hosted by The Gesell Institute staff as well as knowledgeable guest lecturers. All presenters are highly educated, and intensively trained professionals who vary from Early Childhood experts, school superintendents, principals, elementary school teachers, and special education professionals.

Professional Development for early childhood educators and relevant child development information for parents is crucial for ongoing improvement and to ensure high quality learning and growth experiences for all children. Hospitals and medical training institutions need refreshers in the ages and stages of child development for their pediatricians. But choosing relevant learning opportunities that meet the day to day needs of teachers, pediatricians and parents and that truly impact children's lives can be a challenge.

All of The Gesell Institute’s learning programs can be tailored to the needs of a specific group, whether that be through a full day PD training, a half-day workshop, or a 90 minute live seminar or online webinar for teachers or parents. Gesell Institute can provide the professional development training you need as well as meaningful parent programs, presented by the highly trained and experienced National Lecture Staff.

Nurture Children & Youth

When families, schools and communities take the view that children and youth are valued and respected assets to society, they necessarily support environments that nurture youth development. Children raised to embrace positive social values, to seek self-understanding, and to value their self-worth grow to become community-minded young adults with a sense of belonging and a belief in their resiliency. See how you can help our community's children grow into tomorrow's leaders.
