Dalton School

The Dalton School, originally the Children's University School, is a private, coeducational college preparatory school in New York City and a member of both the Ivy Preparatory School League and the New York Interschool. The school is located in four buildings within the Upper East Side of Manhattan. In the 2024–25 academic year, tuition rates totaled $64,300.
The Dalton School, originally called the Children's University School, was founded by Helen Parkhurst in 1919. After experimentation in her own one-room school with Maria Montessori, Parkhurst visited other progressive schools in Europe including Bedales School and its founder and headmaster John Haden Badley in England. She developed what she called the Dalton Plan, which encouraged teachers and students to work together toward individualized goals. The Laboratory Plan was first put into effect as an experiment in the high school of Dalton, Massachusetts, in 1916. The estate of her benefactor Josephine Porter Boardman, was also near the town of Dalton and from this beginning the Laboratory Plan and school eventually took their names.
In 1919, Helen Parkhurst relocated to New York City, where she opened her first school on West 74th Street. Larger facilities soon became necessary; the Lower School was moved to West 72nd Street, and the High School opened in the autumn of 1929 in the current building at 108 East 89th Street. Eleanor Roosevelt admired the work of Helen Parkhurst and played an important role in expanding the population and resources of the school by promoting a merger between the Todhunter School for girls (founded by Winifred Todhunter) and Dalton in 1939.
Enlarged and modified through the years, Dalton still celebrates many traditions like lighting candles before winter break and holding a Greek Festival. Academically, the school still subscribes to the Dalton Plan, which Parkhurst helped to create. Over the years, the Dalton Plan has been adopted by schools around the world, including schools in Australia, Austria, Belgium, Chile, the Czech Republic, Hong Kong, Japan, and the Netherlands.
As of early 2013, the overall acceptance rate for grades K–12 at Dalton was reported by Peterson's to be 14%. Parental anxiety created by the highly competitive admission process was the subject of press coverage from 1999 to 2001. Long seen as a bastion of privilege, Dalton's efforts to broaden its mandate for diversity have met with some difficulty. In 2010, a financial aid budget of $6.5 million supported an outreach program for socio-economic diversity at the school. As of 2008 students of color made up 38% of the Dalton First Program. In the 2008–2009 school year, the kindergarten was composed of 44% children of color. Articles in The New York Times and The Atlantic have described difficulties experienced by some African-American children at the school.
American Promise was a PBS documentary that followed two African American students who enrolled at Dalton as kindergartners and the challenges they faced due to Dalton's lack of diversity. In 2020, Dalton found itself in controversy during the broader diversity, equity, and inclusion movement that followed the murder of George Floyd. The discussions continued into the following school year and resulted in the departure of school head Jim Best.
José Manuel De Jesús became Head of School in 2022. Former Head of School Jim Best resigned in 2021 after 16 years at the school.
