Summary	The Participation and Environment Measure for Children and Youth (PEM-CY) is a caregiver-report instrument that measures how children aged 5 to 17, with and without disabilities, participate in the home, school, and community, and the environmental supports and barriers that shape that participation. Developed by Wendy Coster, Mary Law, Gary Bedell, Mary Khetani and colleagues and published in 2011-2012, the PEM-CY operationalizes the participation construct of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) by asking, for each setting, how often a child takes part, how involved they are, and whether the family desires change, alongside ratings of which environmental features help or hinder. Its distinctive contribution is to measure participation and environment together rather than treating the environment as a separate afterthought.	The Wheelchair Skills Test (WST) is a standardized, objective assessment of how well a wheelchair user can perform a graded set of individual wheelchair skills, from basic maneuvers like rolling forward and turning to advanced ones like descending curbs and performing a stationary wheelie. Developed by R. Lee Kirby and colleagues at Dalhousie University and validated through a 2002 pilot and a 2004 measurement-properties study of version 2.4, the WST scores each skill for whether the user can perform it and how safely, then summarizes performance as a percentage of skills passed. It turns the diffuse notion of wheelchair mobility into a reliable, comparable, and trainable outcome.
