The first home

Holland Hall first moved into a new building in 1923, just south of downtown Tulsa, at 1850 South Boulder. Financing was arranged by a group of prominent Tulsa businessmen, including Waite Phillips and William Skelly. The building contained only nine classrooms. The school outgrew this facility by 1932, when it moved to a new location.^{[5][lower-alpha 1]} By 1930, the school had 60 students and 8 teachers.^[4]

Present home

The campus is 162 acres (0.66 km²) in the southern part of Tulsa. The move to 81st Street began with the Upper Division in 1970. The Primary Division moved in 1976, and the Middle School made the transition in 1982. The 81st Street facility has since added the Walter Arts Center (1992), the Outdoor Sports Complex, including the Charles H. Brown Football Field (1995), the Duenner Family Science, Math, and Technology Center (2000), and Mary K. Chapman Primary School (2009). The football field was renamed Hardesty Field in 2012, when the facade was remodeled and artificial turf was installed.^[4] Each of the three divisions has its own library. In 2018, the A.R. and Marylouise Tandy Dining and Wellness Center was completed, creating a state-of-the-art workout facility for various sports, and bringing Middle School and Upper School dining operations under one roof.

Although the school was intended to be coeducational from the time of its founding, within a few years it became girls-only at the Upper Level (high school age). In 1959, the school became affiliated with the Episcopal church. In the same year, it started a major campaign to attract boys to the upper classes. This included starting an energetic athletic program for boys.^[4]

The school enrolls approximately 1,000 students each year.

The school's "4 A’s" philosophy values academics, athletics, arts, and atmosphere.

Holland Hall offers multiple foreign language possibilities. Beginning in primary school, students learn Spanish. In sixth grade, students take a language of their choice, either French, Chinese, or Spanish. Latin in the middle school was removed after the 2017–2018 school year. Students who need extra enrichment take LAS, Language Arts Strategies, to help with study skills in place of one year of language in middle school. In upper school, students choose between French, Spanish, Latin, and Chinese. Exchange trips and class trips are offered.

Holland Hall is one of only three Oklahoma educational institutions to belong to the Center for Academic Integrity. Holland Hall is one of four independent schools to participate in the College Work Readiness Assessment (CWRA) project. The scores of Seniors in the Class of 2007 were comparable to the top 25% of college freshmen who took the exam at the end of their first year of college.

Middle and Upper school schedules are based on a six-day cycle: A through F. Each day is divided into eighteen twenty-two-minute mods, unless on Wednesday, when school starts an hour later, when it is 18 minute mods. Classes are generally two or three mods long. Each class meets a set number of days per cycle. Freshman Wellness (Upper School), for example, meets two days per cycle, while an English class would meet five of the six. Most of the primary classes (English, math, science, history, foreign language) meet five times per cycle.
