The Gross Motor Function Classification System (GMFCS) is a 5 level classification system that describes the gross motor function of children and youth with cerebral palsy on the basis of their self-initiated movement with particular emphasis on sitting, walking, and wheeled mobility. Distinctions between levels are based on functional abilities, the need for assistive technology, including hand-held mobility devices (walkers, crutches, or canes) or wheeled mobility, and to a much lesser extent, quality of movement.
The focus of the GMFCS is on determining which level best represents the child's or youth's present abilities and limitations in gross motor function. Emphasis is on usual performance in home, school, and community settings (i.e., what they do), rather than what they are known to be able to do at their best (capability). It is therefore important to classify current performance in gross motor function and not to include judgments about the quality of movement or prognosis for improvement.
Children who have motor problems similar to those classified in "Level I" can generally walk without restrictions but tend to be limited in some of the more advanced motor skills. Children whose motor function has been classified at "Level V" are generally very limited in their ability to move themselves around even with the use of assistive technology.
The GMFCS - E&R includes an age band for youth 12 to 18 years of age and emphasizes the concepts inherent in the World Health Organization's International Classification of Functioning, Disability and Health (ICF). We encourage users to be aware of the impact that environmental and personal factors may have on what children and youth are observed or reported to do. The descriptions for the 6 to 12 year and 12 to18 year age bands reflect the potential impact of environment factors (e.g., distances in school and community) and personal factors (e.g., energy demands and social preferences) on methods of mobility.

The recently developed GMFCS Family Report Questionnaire presents an option for parent involvement in classifying children's motor abilities and is available for four age groups of children: 2 to 4 years, 4 to 6 years, 6 to 12 years, and 12 to 18 years, and is also available in French/aussi disponible en français and other languages.
GMFCS E&R Descriptors and Illustrations are available for the 6 to 12 year and 12 to 18 year bands of the GMFCS E&R.

The Motor Growth Curves and Percentiles for children with cerebral palsy describe development of children with cerebral palsy grouped by GMFCS level. These "growth curves" help doctors, therapists, and families understand how the gross motor abilities of children in each level change with age and how much independence children are likely to achieve.
