timeline image - The Beginning of UNIS

Our History Established in 1947

UNIS was established in 1947 by a group of United Nations parents to provide an international education for their children, while preserving their diverse cultural heritages. The school opened its doors in Lake Success, NY to thirty-six children who came from fifteen countries and spoke ten languages.The foundation of the school was to create a program in keeping with the spirit of the United Nations that is one making no distinction as to race, gender, language or religion.

United Nations

Our History 1950

The school was relocated to a group of converted apartments in Parkway Village, Queens. In November 1950 the formal opening of the new quarters included a presentation of the United Nations Flag to the school by Henri Laugier, former Chairman of the International League of Human Rights and ASG for Social Affairs, on behalf of the Secretary-General. The school grew and each year a grade was added.

In 1958, the school was able to move into a vacant public school building at the corner of First Avenue and 70th Street. Six primary grade levels (Junior A, Junior B, Junior C, Junior D, Middle A, and Middle B) accommodated students ages 5 to 10 plus. The Secondary Sequence (Middle C, Senior A, Senior B, Senior C) accommodated students ages 11 to 14 plus. The final two or three years of secondary school consisted of tutorial classes (15 to 17 years plus) offering preparation for national exams such as the American College Boards or the British A and O Level examinations.

Our History 1960

The school was not only referred to as “an important element in the working conditions of the Secretariat" (representative of France) but as “ a challenging educational experiment” (representative of Venezuela), “a centre of international understanding” (representative of Belgium) and “a most successful international venture of its kind” (representative of Uruguay). 

In 1964, Secretary-General U Thant personally undertook the presentation of diplomas to the first class to graduate at the United Nations. In his words, "there, children of different races and nationalities, religions and cultures lived side by side. That intermingling afforded opportunities for combining the technology of the West with the intellectual qualities and philosophy of the East. United by their similarities and enriched by their differences, UNIS pupils were growing and learning in a harmonious atmosphere of work and co-operation.”


Our History 1965

The Ford Foundation offered UNIS a grant of $7.5 million for the construction of a new school building. New York City authorities suggested the possibility of building at the foot of 25th Street on land to be created by filling in or constructing a platform over part of the East River. A special gift of $1 million was offered by the Rockefeller family to meet the cost of developing the site. 


Our History 1967

In 1967 UNIS was one of the eleven schools participating in the newly founded International Baccalaureate Diploma programme. UNIS agreed to accept the diploma as the school's highest standard. The introduction of the International Baccalaureate would particularly benefit those wishing to enter universities in countries other than the United States, but it would also qualify successful candidates for acceptance and for advanced placement in American colleges and universities.



Our History 1971

The painting of Pablo Picasso's daughter Maya was reproduced, with the artist's permission, on a commemorative United Nations postage stamp. The proceeds from the sale of the stamp were to benefit UNIS and the International School of Geneva. The architectural firm of Harrison and Abramovitz was appointed to prepare building plans for the new school in consultation with Ford Foundation specialists and prominent school architects in other countries to ensure that the new UNIS building would incorporate the most progressive ideas in school architecture. In a ceremony in the General Assembly, Secretary-General U Thant dedicated the corner-stone plaque for the permanent UNIS building, thus marking the start of actual construction of a four-story complex that would be able to open its doors to 1,200 pupils in September 1972, on the occasion of the school’s twenty-fifth anniversary.


Our History 1977

UNIS Humanities teacher Sylvia Gordon inspired students to organize a conference on relevant global issues to take place annually in the United Nations General Assembly Hall. She wanted to create a forum at which UNIS students and other students from both local and international schools could meet, discuss and debate critical world issues such as Human Rights, Development, The Energy Crisis, Global Health, Human Trafficking, Disarmament, Population and Migration. Today the conference continues to be completely student run and organized and is shared with over 300 students participating from local and international schools.

Our History 1983

In 1983, UNIS purchased a two-story school building located in the residential neighborhood of Jamaica Estates. This new campus had its own gym, green space, private playground and houses JA (Kindergarten) to 8th grade students.


Our History 1997

In celebration of the 50th birthday of the United Nations School, UNIS held a Festival of the Arts featuring musical performances, film screenings, visual art exhibit and artistic presentations by UNIS students, parents, faculty and staff. A gala dinner was held at the River Cafe in Brooklyn as the culmination of the celebrations.


Our History 2016

Nearly 200 fifth and sixth graders squealed in excitement as they pulled on light blue t-shirts and scrambled to get into lines. "Your Promise, Our Future," read the message emblazoned on the back, and with little fanfare, they all departed the school in the early daylight to make their way to the United Nations. Deep inside the United Nations General Assembly Hall, the students would witness the historic signing of the major climate proposal agreed upon by much of the world the previous November in Paris.



Our History 2017

UNIS celebrates its 70th anniversary by looking at its rich history, the events that shaped the school from its humble beginnings and the successes thousands of students have achieved thanks in great part to their UNIS experience. The education that the school provides---the strong academics and curriculum, the International Baccalaureate, the language, arts, and athletics programmes paired with the experiences beyond the classroom---help prepare students to be global citizens and make significant contributions to shape a better world.

Our History 2020

Like all schools around the world, UNIS had to quickly adjust to the changing environment during the pandemic to continue to provide quality education to our students. In order to strengthen human connections, every week during the COVID-19 lockdown in 2020, UNIS held a Master Class for the entire community, featuring distinguished guests from various fields. Some of the speakers included a US Supreme Court Judge, the Director of the Metropolitan Museum of Art, a Tony Award-winning actor, and the creator of the Daily Show, among others.
