Delphian School

Delphian School is a co-ed K–12 private school operated by Delphi Schools. It uses study techniques created by Scientology founder L. Ron Hubbard, known as Study Tech. It is located on a 720-acre campus in unincorporated Yamhill County, Oregon, near Sheridan. Most students live on campus either full-time or five-day (going home for the weekends). The school also accepts day students; boarders must be at least eight years old, while day students can be as young as five. As of 2024, most of the school's 204 students were in grades 8-12.

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

In 1974, the order sold the building and surrounding acreage to Delphian. The former novitiate was then converted to a boarding school, as it already featured dorm rooms, classrooms, and a dining hall with a commercial kitchen.

Opening in 1976, Delphian School created a curriculum for grades K-12. There were about 60 students in the school's first year. Two years later in 1978 the school had 120 students; tuition was $4,500 for boarding students and $2,800 for non-boarders. 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.

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

During school closures due to COVID-19, Delphian School offered free online classes.

Academics
Delphian School uses a proficiency or competency-based education model. The school does not have letter grades, report cards, or traditional grade levels. Students advance through the curriculum by demonstrating proficiency or competence rather than at a set time.

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. The school is also the location of Heron Books, which published textbooks and materials using Hubbard's educational philosophy (the Delphi Curriculum).

Delphian School is a member of the Oregon Federation of Independent Schools (OFIS), an organization that works to limit government influence on school choice. The OFIS's current director, Mark Siegel, also acts as the school's assistant headmaster. The school is an accredited member of the Northwest Association of Independent Schools, and an accredited member school of Cognia, a standards-based accreditation body.

Activities and athletics
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.

Delphian School started its cheerleading squad in 2013. In 2016, they won the Class 3A/2A/1A state cheerleading title with an overall judged score of 160.70.

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

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.
