Overview of the Peabody Developmental Motor Scales (PDMS)
The Peabody Developmental Motor Scales (PDMS) are standardized assessments designed to evaluate the motor skills of children, typically ranging from birth to five years. These scales measure interrelated motor abilities that develop early in life.
Purpose and Use of the PDMS
The primary purpose of the Peabody Developmental Motor Scales (PDMS) is to assess and evaluate the gross and fine motor skills of children from birth through five years of age. The PDMS is used to identify motor skill deficits, track progress in motor development, and inform intervention planning.
The PDMS helps to determine a child’s relative strengths and weaknesses in motor skills, providing valuable insights for therapists, educators, and parents. It can also be employed to evaluate the effectiveness of motor skill interventions and programs. The assessment is useful in educational therapy because it assesses both qualitative and quantitative aspects of the child’s motor performance.
Furthermore, the PDMS aids in diagnosing motor delays or impairments in children with conditions such as cerebral palsy or developmental coordination disorder. The information gathered from the PDMS can then be used to create individualized education programs (IEPs) and intervention strategies to support the child’s motor development. The complete assessment kit includes the necessary materials for administration and scoring.
Age Range Assessed by the PDMS
The Peabody Developmental Motor Scales (PDMS) are specifically designed to assess motor skills in children within a defined age range. The PDMS can be used to measure both gross and fine motor development of children in the age range from birth through 83 months (6 years, 11 months).
This broad age range allows professionals to evaluate motor development from infancy through the preschool years. The scales are structured with age-appropriate items, ensuring accurate assessment at various developmental stages. This includes assessing early motor milestones in infants, such as rolling and sitting, as well as more complex skills in older children, like jumping and throwing.
The PDMS provides a comprehensive view of a child’s motor abilities across this critical period of development. The PDMS-2 also measures motor abilities of children from birth to 5 years of age, offering valuable insights into a child’s motor progress and potential areas for intervention.

Check for institutional guidelines regarding acceptable versions.
Subtests and Scoring of the PDMS
The PDMS includes several subtests evaluating different aspects of motor skills. Scoring involves observing a child’s performance and comparing it to normative data to determine developmental levels.
Core Subtests: Gross and Fine Motor Skills
The Peabody Developmental Motor Scales (PDMS) comprehensively assesses motor skills through core subtests focused on both gross and fine motor functions. Gross motor skills, involving larger muscle movements, are evaluated through subtests like reflexes, stationary movement, locomotion, and object manipulation. These assess abilities such as balance, coordination, and movement across space. Fine motor skills, which involve smaller muscle movements, are assessed through grasping and visual-motor integration subtests.
These fine motor subtests evaluate a child’s ability to manipulate objects, hand-eye coordination, and dexterity. The assessment of both gross and fine motor skills provides a detailed understanding of a child’s motor development. This dual focus enables examiners to identify specific areas of strength and weakness, allowing for targeted intervention and support to promote optimal motor development in young children.
Composite Scores: Gross Motor Quotient, Fine Motor Quotient, and Total Motor Quotient
The Peabody Developmental Motor Scales (PDMS) yields three key composite scores that provide a comprehensive overview of a child’s motor abilities. The Gross Motor Quotient (GMQ) is derived from the gross motor subtests, reflecting overall performance in activities involving large muscle groups, like running and jumping. The Fine Motor Quotient (FMQ) is calculated from the fine motor subtests, indicating proficiency in tasks requiring precise hand-eye coordination and dexterity, such as drawing and grasping small objects.
The Total Motor Quotient (TMQ) is an aggregate score that combines the GMQ and FMQ, offering a holistic measure of overall motor competence. These composite scores are standardized, allowing for comparison to normative data and identification of motor delays or deficits. They are essential for creating targeted intervention plans and monitoring progress over time, providing valuable insights into a child’s motor development trajectory.
