How do the GDO-R and the Gesell Early Screener (GES) differ?

The Gesell Developmental Observation-Revised (GDO-R) is an in-depth, multi-dimensional child assessment. Its purpose is to help educators, parents, and other professionals understand characteristics of child behavior in relation to typical growth patterns. The GDO-R provides a Developmental Age based on in-depth interpretation of the developmental items, as well as strand scoring in The Gesell Early Screener (GES) is an early screener, based on selected GDO-R items. It provides just a quick look at the child and is intended for use with 3 to 6-year-olds. It has fewer items than the GDO-R, takes less time, is scored objectively, and results in a simple, three-tiered scoring rubric. No Developmental Age is provided.

What does the GES’s “three-tiered scoring rubric” mean?

Based on the national 2010 technical data sample, the simple scoring rubric for the Gesell Early Screener generates one of three levels for the child. Children scoring in one tier have responses that are essentially average or above average for their age level, indicating no concerns about development at the time of the screening. Scores in a second tier indicate a pattern of non-ideal responses relative to the child’s age level that prompts mild concern. A child scoring at this tier may need more attention or more individualized instruction, and it would be appropriate to watch the child more closely and retest. Children who score at the third tier exhibit responses that deviate well below the average for their age level and may benefit from an in-depth assessment and observation.

Why would I use the Gesell Early Screener if the GDO-R is so much more in-depth?

Both the GDO-R and the GES provide knowledge about the child. However, the Screener does so in a much more quick and easy way for the 3-6-year-old child. It is truly a quick screener. As such, it does not provide the in-depth information that the GDO-R provides. The screener provides a quick look at the child with objective academic and developmental tasks, in approximately 15-20 minutes.

The Screener also flags if further testing is necessary. What’s more, the GES meets federal mandates for Head Start and IDEA requirements as a quick screener. It not only helps obtain the information needed under these mandates but also helps to meet documentation requirements.

Why should I purchase the GDO-R or Gesell Early Screener (GES)?

The updated technical data and resulting child trends now qualify our assessments to meet the rigorous standards set by the federal government and the American Psychological Association for appropriately meeting the early learning needs of children. By choosing to purchase the GDO-R or the GES, you are endorsing not only a respect for child development but a method of child study that dates back to Arnold Gesell’s historic work at Yale University.

Data from the 2010 national GDO study the Institute conducted backs each and every item on both instruments, including two sub-studies for scoring and interpretation of Developmental Age. The GDO-R and GES support Gesell Institute’s view that ‘a child is more than a score.’

How do the GDO-R and the Gesell Early Screener meet IDEA and Head Start mandates?

The GDO-R system and the Gesell Early Screener (GES) kit meet evaluation requirements for both Head Start (§ 1304.20) and Section 614 of IDEA (Individuals with Disabilities Education Act). Namely, both systems meet the following guidelines. In collaboration with each child’s parent…obtain linguistically and age appropriate screening procedures to identify concerns regarding a child’s developmental, sensory (visual and auditory), behavioral, motor, language, social, cognitive, perceptual, and emotional skills.

Screening procedures are sensitive to the child’s cultural background. (Assessment system) utilizes multiple sources of information on all aspects of each child’s development and behavior, including input from family members, teachers, and other relevant staff who are familiar with the child’s typical behavior. Use technically sound instruments that may assess the relative contribution of cognitive and behavioral factors, in addition to physical or developmental factors.

Why should I include the GDO-R or Gesell Early Screener in my college or university assessment courses

Assessment courses typically involve exposing students to an array of measurement types and methodologies through currently used assessment tools. Gesell assessments have been widely used across the country for 70 years. The Psychological Corporation published the first version of the GDO in 1940. The current assessment system, titled the GDO-R, has been updated with technical data from a national sample of 3-6 year olds.

The Gesell Early Screener consists of a subset of GDO-R tasks and provides a quick developmental profile for the 3 to 6-year-old child. The GDO-R, a longer but more comprehensive developmental assessment, requires a 3-day training workshop for in-depth scoring and interpretation; the GES requires no training. Both measures are excellent additions to any assessment course.

What kind of validity and reliability do the GDO-R and Gesell Early Screener have?

Content validity was derived by asking experts in the early childhood field the following questions: Does the content of the old GDO reflect the information teachers need/want to know? Is the old GDO content age appropriate? Is the method for soliciting the information appropriate for children? Is the method for soliciting the information appropriate for teachers? Is the method for soliciting the information appropriate for parents/guardians? Is there any bias for gender, race, age, disability, or socio-economic status?

An online survey and a subsequent focus group of current users of the GDO ©2007 were asked similar questions. Evidence of construct validity comes from the GDO-R and Gesell Early Screener (GES) being based on established theories of child development. Inter-item correlations of the GDO-R and GES also provide evidence of construct validity. Reliability was established by calculating internal consistency coefficients and conducting an inter-rater reliability study.

I teach/study developmental theory but I'm not that familiar with Dr. Arnold Gesell. Why is Gesell theory important?

Arnold Gesell, PhD, MD was a pioneer in child development, beginning his groundbreaking work in the early 20th century. He developed a set of norms illustrating sequential and predictable patterns of growth and development, used as the basis of the 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 the nation’s first school psychologist. He was also a founding member of the National Association for Nursing and Education, now known as the National Association for the Education of Young Children (NAEYC).

Working at Yale from 1911 to 1948, Gesell used innovative methods of observation and cinematography to delineate the process of the ages and stages of normative development. Gesell was the first to recognize these stages, which have since become well established in modern day pediatrics and psychology. Gesell sought to document the process of growth for the whole child, believing, as we do today, that “a child is more than a score.” Additional details about Gesell’s maturational theory are provided in the updated GDO-R Examiner’s Manual, along with how this theory ties into the work of other well-known theorists such as Piaget and Vygotsky.

Why is it important to understand that all children are individuals?

No two children are alike. Even those of the same age in the same family differ remarkably from one another, each experiencing growth and development in a unique way, at an individualized pace. Many important factors contribute to a child’s individuality including his or her developmental pace, heredity, temperament, intelligence, health, as well as cultural and environmental influences. These all affect the way he or she grows and learns. When parents, teachers, and others view and respect each child as an individual with unique abilities, competencies and needs, they can better support healthy growth & development.

What is the Developmental Point of View?

The developmental point of view requires that we view children as individuals and as whole beings. The physical, social, emotional, and intellectual aspects of development depend on and support each other and should advance in concert, that is, one aspect of development should not be pushed ahead of others. The developmental point of view appreciates that readiness for any task has its roots in the biological makeup of the child, in combination with environmental influences. Since we cannot produce, speed up, or ignore readiness, we are required to understand and respect developmental ages and stages, which indicate where a child is on a developmental spectrum now, not where we think he or she should be. This is not to say that we cannot or should not formulate expectations for behavior or performance, but rather that these expectations are based on a sound understanding of what is developmentally appropriate for the various ages and stages of growth.

Why is it important to understand Developmental Age?

While all children typically grow through patterned and predictable stages of development, each child progresses through these developmental stages at his or her own rate. Through systematic observation, an individual child’s behaviors and performance can be correlated to normative patterns that have been established for each developmental age. Determining a child’s developmental age or stage can provide valuable information for parents, educators, and other adults who interact with or act on behalf of children, allowing them to not only view the child as an individual, but also to understand the distinguishing characteristics, abilities, and needs associated with various developmental stages. As such, expectations at home, in school, and in the community can be adjusted accordingly.

What can I do to speed up or enhance my child’s development?

Your role and responsibility in your child’s growth and development is very important. First realize, however, that developmental growth and learning, while not automatic, is a natural process that proceeds at different rates in different children. Certain developmental skills are typically achieved within a range of ages but not according to a rigid schedule or timetable. A child may be anywhere within that range.

A child should not be pushed to develop more quickly – development is a fluid process that cannot be rushed. Experiences can enhance development, but cannot speed up a child’s rate of growth.

Regardless, you can and should engage your child in a large variety of enriching and meaningful experiences that enable him or her to grow more fully in skill and confidence, within his or her own developmental stage. Positive early experiences are critical for brain development, helping to prepare a child for better learning at later ages.

What is developmental observation or assessment, and why is it important?

Developmental assessment is used to determine whether a child has reached developmental milestones and can accomplish the major associated tasks. Individual children’s responses are matched with normative patterns of behavior for each age. The responses yield a description of the child’s Developmental Age in contrast to chronological age.

An important aspect of developmental observation or assessment is that it can highlight areas of concern, and administered over time, can monitor consistency among developmental domains. When developmental assessment reveals signs of difficulty, re-screening should follow after a short interval. Persistent signs of difficulty indicate the need for a referral for diagnostic assessment.

Understanding children in light of their developmental age can help to adjust expectations, inform curricula, design spaces, and establish practices that are developmentally appropriate and supportive of the natural unfolding of the growth and development process.

What is a 'Developmental Approach' in the classroom?

The aim of education is, or should be, to promote the total development of each child. Language, social-emotional, physical, and cognitive growth and development must all be major considerations in the classroom. Educators who understand whole-child development know the importance of classroom programs that seek a balance between active, child-initiated learning and teacher-directed instruction. The success of this approach rests on the ability to bring to the classroom an understanding of child behavior, developmental learning theory, and a flexible curriculum through the following principles,

• All children, especially young children, learn best in environments arranged with 
attention to individual levels of developmental growth.

• Children are individuals, who grow through developmental stages in their own unique way and at their own pace. The ability to observe and understand these differences is essential to successful classroom planning.

• Evaluation of children’s growth should be gathered from a variety of sources and methods, including parents and guardians, classroom observation, portfolios, developmental assessment, and other appropriate records.

• Teachers need to be close observers of children’s readiness for new levels of content, skills, and activities. A clear understanding of given activities and their relationship to a child’s present level of development is extremely important.

• Classrooms with a developmental approach should be structured with trust in children’s natural abilities. This encourages self-learning through active participation and interaction with teachers, classmates, and classroom materials.

Why is developmental observation important for schools?

A picture of where children are in their individualized growth through the developmental stages, gained through systematic observation, informs teachers of the uniqueness of each student in the classroom and, collectively, of their diverse abilities and needs. Ideally, this information is used to help design curriculum and to adjust curricular expectations, so that all children can feel secure and successful in school.

What about preschool?

Preschools, educational stimulation, and other environmental factors can support and enhance development and foster curiosity, but they cannot hurry or change the overall development of any child, nor can they speed up a child’s unique rate of growth and development. A quality preschool provides the experiences and opportunities that are appropriate for that age and stage of development, but these experiences do not set a timetable for development.

Research does show that a quality preschool experience can better prepare our youngest learners to meet the curricular expectations of kindergarten. All children have the right to and deserve the opportunity for quality early childhood educational experiences, and there is a move toward universal access to preschool in many states.

Parents able to send their children to preschool should consider programs that have been designed to support the development of the whole child, encourage the child’s love of learning, and to respect individual differences among children.

When is a child ready for Kindergarten?

Much has been written about school readiness. Although experts cannot agree on an exact definition of school readiness, most agree that all schools should be ready for all children who are age eligible to start kindergarten. Unfortunately, however, the reality is that it is the child who most often has to be “ready” for school rather than the other way around.

Typically, a child must be five years old, or close to five years to begin Kindergarten. However, not all 5-year-olds are developmentally ready for the rigors of an increasingly academic and demanding Kindergarten curriculum. A child may already know the ABC’s or be able to count to 100, but a child also needs to be ready physically, socially, and emotionally, and exhibit behaviors that will support school success. Depending on the expectations of the individual Kindergarten setting, a regular education child may need to be able to sit for long periods of time quietly, take care of personal needs independently, understand and respect rules and limits, and work without a lot of adult supervision.

Many children of the same chronological age may differ remarkably from one another in their rates of growth and development. These differences are often not compatible with Kindergarten programs that have rigid curriculum standards designed to meet prescribed criteria for academic performance rather than to meet the individual needs of the child. Parents should be encouraged to talk to teachers and administrators at their child’s school to better understand the school’s expectations and whether or not the environment is most appropriate – and ready – to meet the needs of their child.

Not all children are ready for the same experiences at the same time. As such, parents may want to consider not only the particular curricular expectations of the Kindergarten, but also signs of the child’s developmental readiness for that particular program. Discuss this with teachers or administrators at your child’s school, and think about the following questions. Please ask yourself: Can my child……

• Comfortably be away from me for an entire day?

• Express ideas and feelings to adults other than immediate family?

• Accept minor disappointments or limits without tears?

• Listen to, and follow, directions?

• Take turns, and/or wait for his/her turn, patiently?

• Work independently without constant adult supervision?

• Find ways to resolve conflicts and solve problems with peers independently? 

• Make simple decisions given a few choices of play activities? 

• Take care of personal belongings and toileting needs independently?

• Retell familiar stories, nursery rhymes, or songs?

Should a child repeat a grade?

Research has shown that retention after Grade 1 results in no significant academic gains for children. What this tells us is that retaining a child due to concerns over academic failure later in the school career will not usually produce the desired results of “catching up” and succeeding in school. On the other hand, children who are not developmentally on the same level as their chronological peers may benefit by an extra year of preschool, Kindergarten, or first grade; depending on the circumstances, the individual child and school environment.

While we do not suggest that waiting a year before entering Kindergarten or retaining a child in any grade is the best solution for all children, and we recognize that this simply is not an option for many families, particularly those without access to quality preschool settings, it may be a viable option for some children and in some schools. In certain cases, waiting a year may “level out the playing field” so that development can catch up with chronological age, or age and development can catch up with the school’s expectations.

It is important to understand that parents should be fully involved in the decision of whether or not to retain a child, and have every right to be involved in that decision. Academic differences in the classroom can be accommodated in school much more easily than wide differences in developmental stage, but both can be addressed in the ideal setting with ideal resources and supports.

If you are concerned about a recommendation to retain your child, talk to your child’s teachers, express your concerns, and know that you are your child’s first – and best – advocate.

What constitutes a positive learning environment for children?

A positive learning environment respects the child and the child’s level of development. Some characteristics of a positive learning environment include greeting the children when they arrive, addressing children by name, and extending invitations for children to interact with the teacher. Children are spoken to politely and listened to attentively when they are speaking. Children are invited to elaborate on what they are saying and allowed long enough time for them to gather their thoughts. This is important to help children feel invested in the learning process.

Taking advantage of spontaneous opportunities to converse with children is rewarding for both students and teachers! At the very least, children in any classroom with a fixed curriculum should be understood and treated as individuals. The delivery of the curriculum should be tailored to meet their unique and differing needs.

Accordingly, school programs should not treat all children as ready for the same thing at the same time. Recognition of differences in rates of growth among children who are the same chronological age should be used to help plan and guide school structure and curricula.
