A laboratory school or demonstration school is an elementary or secondary school operated in association with a university, college, or other teacher education institution and used for the training of future teachers, educational experimentation, educational research, and professional development.
Many laboratory schools follow a model[citation needed] of experiential education based on the original Laboratory School run by John Dewey at the University of Chicago. Many laboratory schools are still in operation in the United States and around the globe. They are known by many names: laboratory schools, demonstration schools, campus schools, model schools, university affiliated schools, child development schools, etc., but all have a connection to a college or university. Each university affiliated school has a unique relationship with a college or university and a different grade configuration. Some lab schools are only for preschool or kindergarten children, some are preschool through fifth or sixth grade, and some continue through high school.
