Education Laboratory School is a charter school in Honolulu, Hawai‘i serving grades K-12. Prior to 2002, the school was known as the University Laboratory School or University High School (when referring to grades 9 through 12) when it was a part of the College of Education at the University of Hawaiʻi at Mānoa. It is not to be confused with Punahou School, which occupied some of the buildings at the university when they were displaced from their campus by the U.S. military during World War II.HistoryThe school was originally founded as a place for education majors at then Teacher's College at the University of Hawaiʻi to practice their teaching skills. Between 1939 and 1941, an elementary school was built to give elementary and pre-school education students hands-on experience. A permanent building for this purpose, Castle Memorial Hall, was constructed at this time. It was a gift of Mary and Samuel Castle, who was one of the founders of Castle & Cooke.Punahou School occupied Castle Memorial Hall and other buildings at the college during World War II (1942–1945). However, the college continued to operate.Buildings for the high school were constructed after the war with University High School Building 1 opening in 1943 and University High School Building 2 opening in 1948. University High School Building 3 opened in 1957. Finally, the Multipurpose Building is opened in 1963. In the mean time the school graduated its first high school class in 1951.In 1966, the school's focus changed to testing curriculum developed by the college for use in the Hawai'i Public School system under what is now called the Curriculum Research and Development Group (CRDG). Since this time, admission to the school is based on creating a cross section of the state's socio-economic groups to meet the needs of the testing of the curriculum materials. Over the years CRDG increased its marketing area of the materials they develop to across the United States and then internationally.
