Dalton public schools

'The Dalton School' in New York is the mother of all Dalton schools
in the world. That excellent private school proves already for so
many years the value of Helen Parkhursts 'Dalton Laboratory Plan'.

Their Mission Statement:
The Dalton School is committed to providing an education of excellence that meets each student’s interests, abilities and needs within a common curricular framework and reflects and promotes an understanding of, and appreciation for, diversity in our community as an integral part of school life. Dalton challenges each student to develop intellectual independence, creativity and curiosity and a sense of responsibility toward others both within the School and in the community at large. Guided by the Dalton Plan, the School prepares students to “go forth unafraid.”
