ʻIolani School, located at 563 Kamoku Street in Honolulu, Hawaiʻi, is a private coeducational college preparatory school serving over 1,800 students.^[2] Founded in 1863 by Father William R. Scott, it was the principal school of the former Anglican Church of Hawaiʻi. It was patronized by Kamehameha IV and Queen Emma who gave the school its name in 1870. ʻIolani in the Hawaiian language means "heavenly hawk". Today, ʻIolani School is affiliated with the Episcopal Church in the United States. It is administered by a Board of Governors and is one of the largest independent schools in the United States.^[3]

On October 11, 1862, Lord Bishop Thomas Nettleship Staley arrived in Hawaiʻi by request of Kamehameha IV and Queen Victoria of the United Kingdom. The following year Kamehameha IV, a devout member of the Church of England, established the Hawaiian Reformed Catholic Church, also known as the Anglican Church of Hawaiʻi. The school was originally named for Saint Alban.

In 1863, Staley's companion Father Scott purchased land in Lāhaina and established Luaʻehu School, a school for boys. When Father Scott fell ill and returned to Britain, Father George Mason was summoned by Staley to administer the school on Maui. On January 12, 1863, the St. Alban's College was also established in the Pauoa Valley in Honolulu. Mason also seemed to have managed this school as well. Before Staley, too, left the islands for Britain in 1870, Father Mason merged the two schools and relocated it to the St. Alban's campus. Later Bishop Alfred Willis purchased land on Bates Street in Nuʻuanu Valley and moved part of the school there, intending it for students of full or part Hawaiian descent, under the new name of ʻIolani College. The St. Alban's College, intended for white students, separated and continuing operating at Pauoa until 1887.^[4][5][6]

With the overthrow of the Kingdom of Hawaiʻi and annexation to the United States in 1898, the Anglican Church of Hawaiʻi became part of the Episcopal Church United States (ECUSA). ʻIolani School was moved to Nuʻuanu, transferred back to downtown Honolulu and then moved to Nuʻuanu a second time. It remained in Nuʻuanu from 1927 to 1953, when it was moved to the present Ala Wai site.

In 1979, the school became co-educational, ending its all-male enrollment policy.

ʻIolani School grew and refined its program offerings with a standard college preparatory curriculum as a foundation for every student. Religion, performing and visual arts, music and athletics became integral parts of the ʻIolani School education, i.e., in the sixth grade, all students must be involved in a performing art.

The campus is divided into Upper and Lower School. Buildings include Castle Building, Weinberg Building, the I-Wing, the art building, and the Nangaku Building. Other facilities include the Upper Gym and the Lower Gym, the Ranzman Library, the Dillingham Pool, and St. Alban's Chapel. ʻIolani School also has a stadium (Kozuki Stadium), a baseball field, an outdoor basketball court (the One Team Field house), and several tennis courts.^[7]

The Sullivan Center for Innovation and Leadership was finished at the end of 2012 for the replacement of the Upper School Library. The Sullivan Center was created to emphasize sustainability.

The Harold K.L. Castle Building was dedicated in 1980 to the Castle Family which had donated land to 'Iolani School. The Castle Building also contains most classrooms for the 7th and 8th Grade.^[8]

ʻIolani School's athletic program was founded in 1932 by Father Kenneth A. Bray. Over 900, or 70%, of the student body participates in one of over 32 competitive sports. ʻIolani School is a member of the Interscholastic League of Honolulu, an athletic conference composed of Honolulu-area private schools.

Since the formation of the Hawaii High School Athletic Association, ʻIolani has won over 75 state championships in various sports. It is the only school in Hawaiʻi to have won five consecutive state championships in Boys Basketball from 2002 to 2006.^[9] ʻIolani has the most consecutive state championships in Boys Wrestling, and is the first ILH school to win a Girls Wrestling State Championship in 2005.^[10] They also have eight consecutive D-II football titles, highest in the nation.^[11]

ʻIolani School's campus is divided into two sections: Lower School and Upper School.

Lower School is for elementary students, kindergarten through 6th grade.^[12]

Upper School is for 7th through 12th grade. The schedule has eight periods, which rotate weekly. Each student normally has one study hall/free period and one elective, although new students who do not take a language normally have a second study hall or elective. Iolani summer school allows students to earn graduation credits; credit courses offered during summer include art, history, science, computers, and language.^[13]

Harold Keables was first a teacher in Denver, where he was named the National Teacher of the Year by Life magazine;^[14] in 1965 he started teaching at ʻIolani School.^[15][16] Each year his legacy is honored via the Keables Chair, which brings "outstanding teachers, writers, and artists to ʻIolani."^[17]

ʻIolani students are involved in many extracurricular activities.

'Iolani has two Science Olympiad Teams, Division B (grades 6-9) and Division C (9-12).

Division B has been a part of Science Olympiad since 2012.^[20] They have qualified for the national tournament twice (in 2012 and 2014).^[21][22] For every other year they have competed, they have been the runner-up at the states competition.^[21] In the 2012 National Competition, Division B placed 5th in Water Quality.^[23]

Division C has been a part of Science Olympiad since 2011.^[20] They have qualified for the national tournament every year they have competed, except for 2013 when they placed as runner up.^[21] At the 2014 national tournament at the University of Florida, the team was the national champions in the trial event Hydrogeology.^[24] At the 2015 national tournament at the University of Nebraska-Lincoln, Division C was the national champions in both Fossils and Geologic Mapping and placed 2nd in the trial event Science Bowl.^[25] In the 2016 National competition, the Division C team was the national champions in Fossils, and placed 3rd in Game On and Anatomy and Physiology, and 4th in Geologic Mapping.^[26] They also placed 2nd in Game On and 3rd in Indoor Bottle Rocket at the 2017 National competition.^[27]
