Campus and historyEdit

In the fall of 1976, the Delphian School opened on the site of a former Jesuit novitiate near Sheridan, Oregon.[8][9] The main building on campus is a four-story, Art Deco-style building with a brick exterior that was designed by Poole & McGonigle and built in 1933 for the Jesuit house.[10]

An estimated 60 students were enrolled in the school's first year.[11] Two years later in 1978 the school had 120 students; tuition was $4,500 for boarding students and $2,800 for non-boarders.[9] In the mid-1980s the campus was considered as a possible location for a federal prison. The Sheridan Federal Correctional Institution opened in 1989 in another location in the area.[12][13][relevance questioned]

The headquarters for Delphi Schools, Inc. are located at The Delphian School, which is the founding school.[14]

During school closures due to COVID-19, the Delphian School offered free online classes.[15][16]


The Delphian School is operated by Delphi Schools using L. Ron Hubbard's study techniques, known as Study Tech. The Study Tech teaching methodology is licensed through the Scientology-related group Applied Scholastics.[5] The school is also the location of Heron Books, which published textbooks and materials using Hubbard's educational philosophy (the Delphi Curriculum).

The school uses a proficiency- or competency-based education model. There are no letter grades, report cards, or traditional grade levels at the school. Students advance through the curriculum by demonstrating proficiency or competence rather than at a set time.[17]

Delphian School is a member of the Oregon Federation of Independent Schools (OFIS),[18] an organization that works to limit government influence on school choice.[19] The OFIS's current director, Mark Siegel, also acts as assistant headmaster of the school.[20] The school is an accredited member of the Northwest Association of Independent Schools, and an accredited member school of AdvancED.[1][2]


The Delphian School's sports team is known as the "Dragons". The school participates in the Oregon School Activities Association's (OSAA) Northwest League, 2A classification, for girls and boys sports: basketball, tennis, cross country, track and field, boys soccer, volleyball, and cheerleading; and for such other activities as speech and debate, solo music, and choir.[21]

In 2014 the Delphian choir tied for the OSAA Choir State Championship. That year three school soccer players were named to the All-State team.[22][23]

In 2013 a student was chosen as the youth delegate to Youth for Human Rights International, a Scientology-related organization.[24]
