The Bucknall campus houses the Lower School (kindergarten through grade 5), the Union campus houses the Middle School (grades 6–8), and the Saratoga campus houses the Upper School (grades 9 through 12). Harker School's tuition is higher than comparable private schools in the Bay Area. Many of the 35+ after-school programs have historically been included in the tuition. As of 2026, annual tuition for the Lower School is $51,550, compared to $61,450 for the Middle School, and $66,950 for the Upper School. The San Francisco Chronicle noted that tuition at the most expensive private schools in the Bay Area, including Harker, exceeds "two of California’s top private colleges, Stanford University and Santa Clara University," and "far exceed undergraduate tuition rates for public colleges."

As with many schools in the Bay Area, finding housing for teachers has been challenging due to the ongoing housing crisis in the area. As such, in 2022, the school purchased two apartment buildings to convert to faculty housing for $3.8 million. The effect was the displacement of up to eight families who lived in the apartments. The school was said to provide some aide to assist with moving costs for those families, though the amount was not specified. In August 2023, a 9-year-old girl, who had been participating in a summer program at Harker School was found unresponsive in the elementary school pool. Lifeguards and school nurses attempted lifesaving procedures, however the girl died. Camp was cancelled for the rest of the week, and the school provided mental health services to campers, students, and staff.

The upper school, offering grades 9 through 12, is located on the Saratoga Avenue campus. The campus was previously home to an all-girls school, Mother Butler Memorial High School, which merged with Archbishop Mitty High School in 1969. The upper school was added to the K–8 program in 1998, with the first class of graduates in 2002.

The middle school is located on the Union campus, the former site of the Harker Preschool. Since the opening of the upper school in 1998, most students choose to remain at Harker School after middle school.

The elementary school is located on the Bucknall campus, the former site of Bucknall Elementary School. The campus was purchased by Harker School in 1997. The lower school also has an after-school orchestra, as well as sports and other activities.

In 1902, Miss Harker's School was founded by Catherine Harker as a girls day school, with a limited boarding school, also located in Palo Alto. In 1917, the enrollment was 40 girls and it served as a preparatory school for competitive colleges such as Stanford University. From 1902 to 1907, Miss Harker's School was located at 1121 Bryant Street in Palo Alto; and moved to 1050 Greenwood Avenue in Palo Alto, where the campus expanded and the nearby streets were renamed (Melville and Harker Street) to reflect the campus.

In 1891, Stanford University founding president David Starr Jordan influenced Frank Cramer to open the Palo Alto Preparatory School for Boys. The school was renamed Manzanita Hall in 1892, and by September 1894 the school enrolled 24 students. In 1893, the school was a boys day school and boarding school. The Manzanita Hall school began at 1129 Parkinson Avenue in Palo Alto, California. In 1915, the enrollment was 60 boys. in 1919, Manzanita Hall was purchased and renamed Palo Alto Military Academy, which remained until 1972.

In 1972, the Palo Alto Military Academy and Miss Harker's School merged to form the Harker Academy. With the merger, the school moved to 500 Saratoga Avenue in San Jose, California. in 1993, its name changed to The Harker School. In 1954, the Harker School joined the California Association of Independent Schools (CAIS) and the Western Association of Schools and Colleges.
