Many questions about our program are answered elsewhere on our site—such as, What are forms? How independent is independent study? What are the age ranges of your Lower, Elementary, Middle and Upper Schools?

For those questions not answered elsewhere, you can hopefully find your answer below. If not, please contact our Admissions Office. We welcome your questions about our school and program.

What is an independent school?

Independent schools are private learning institutions with missions unique to each. In order to be considered 'independent,' such schools must be not-for-profit institutions governed by independent boards of trustees and funded through tuition, charitable contributions, and endowment income.

Independent schools uphold high standards of educational quality and are publicly accountable to parents, communities, and the agencies that accredit them. Delphian School is accredited by the Northwest Association of Independent Schools,, through a rigorous self-study process comparing our mission and values against the NWAIS standards, which include cultivating excellence in school leadership and academic rigor, furthering diversity, equity and inclusion, encouraging free and open inquiry, and fostering collegial and collaborative relationships, among many others.

Does the Delphian School have any religious affiliation?

Delphian School is a fully independent, non-religious, K-12 day and boarding school welcoming students of all faiths.

Delphian does not have any religious affiliation. The school pays no fees or tithes to any church and does not teach the doctrines of any one faith, although students will study a course entitled Understanding the Classical Religions in their senior year. This course covers the basic tenets of Christianity, Judaism, Islam, Hinduism, Buddhism and Confucianism and includes reading from their respective religious texts.

What is the true cost of a Delphian education?

Delphian tuition covers the costs related to most student experiences, including field trips and experiential activities, practical projects, community service, and often travel to apprenticeships and internships.

For Middle and Upper School students there are additional materials fees, and for Upper School students there is the cost of a laptop and a technology fee. Please see the Tuition & Fees page for details.

Can my family apply for a scholarship or financial aid?

Yes. Please visit our Affording a Delphian Education page for more information.

Do young children board at your school?

Delphian School accepts boarding students from the age of 10, but the majority of our boarders are of high school age, with a smaller percentage at the middle school level (around 20% between ages 12 and 13).

Our elementary and lower schools primarily service local families whose children attend our day (non-boarding) programs.

Because younger children need a greater level of care and attention than older students, all boarding students enrolling in the Elementary and Middle Schools are assigned personal teachers (PTs). The PT is a faculty or staff member who helps provide the extra care and attention needed by a child of this age group who is living away from home.

PTs assist the parents by overseeing the welfare of younger boarding children in a variety of ways, such as eating most meals with their students, visiting with them at bedtime and spending time together on weekends.

Isn't boarding school mainly for children with behavioral or learning problems?

While some boarding schools cater to children with specific needs, the majority of boarding schools have the general mission of offering excellent educations that by statistic far exceed other private day and public schools in a number of important areas.

Boarding School Facts

The Art and Science Group conducted a nationwide survey of over 2,700 high school students and adults regarding their experiences in high school and their lives since. The survey found that, compared to day students, boarding students:

  • Devote more time to homework and extracurricular activities: 17 hours/week, versus 9 hours (private day) and 8 hours (public).
  • 90% of boarding students report having high quality teachers - versus 62% (private day) and 51% (public).
  • 78% of boarding students said they were well prepared for college - versus 36% (private day) and 23% (public).
  • 56% of boarding students go on to earn advanced degrees - versus 36% (private day) and 21% (public).

In fact, the survey found that 60% of students applied to boarding school primarily for the opportunity to get a better education.

The above survey also offered the following key findings:

  • Students at private boarding schools have a better experience in high school than do students of a similar profile in public and private day schools.
  • Students at private boarding schools are better prepared for and attend more prestigious colleges and universities than do students of a similar profile in public and private day schools.

The Association of Boarding Schools has done extensive research into the quality of boarding school education and its long term benefits to students. Visit for more information or for additional statistics and survey findings.

Sending a child of any age away to school is an important decision for any family. To be accepted at Delphian, both the child and the parents must want to be here for the right reasons. We do not accept children who are being 'sent away' for various reasons, only those who want to tackle their own education head-on.

Our Admissions team spends many hours with each applying family to ensure Delphian is the right fit for both the needs of parents and the child. Please reach out to them for more information. They welcome your questions and calls.

How are children of differing faiths supported?

Delphian School admits students from around the world and has hosted a student body representing as many as twenty different nations. As a result, there are children in attendance who are members of many faiths, including Christianity, Hinduism, Buddhism, Islam, Judaism and Scientology, and representative of different denominations and sects.

In coordination with each child's parents, Delphian School helps arrange transportation to local churches, synagogues or temples on days of worship as required by a student's individual religious practice.

How is Delphian School associated with L. Ron Hubbard?

L. Ron Hubbard was a writer, an engineer, a philosopher, an educator and a researcher whose discoveries and writings cover a wide range of secular (non-religious) activity.

Mr. Hubbard studied and wrote at length about methods of learning which markedly improve a student's ability to understand and apply what is being studied. These breakthrough methods are part of the study tools learned by all Delphian students.

Mr. Hubbard also researched and wrote extensively on the subjects of logic, ethics, leadership and communication. Delphian students study these subjects, and some of their materials include data selected from Mr. Hubbard's secular research in these areas.

Mr. Hubbard's book entitled, The Way to Happiness, is a non-religious moral code, and students study this work to understand the basic, common-sense moral agreements that we expect all members of our community to follow.

How is Delphian associated with Applied Scholastics?

Applied Scholastics is a non-profit, public benefit organization formed in 1972 by educators from colleges, universities, and both public and private schools. The mission of Applied Scholastics is to provide effective education services and materials that help people learn how to learn and thereby work effectively to achieve their goals and realize their full potential.

Delphian School is licensed by Applied Scholastics International to use the study methods developed by Mr. Hubbard.

Does the Delphian School teach the Scientology religion?

No. Delphian School does not teach the Scientology religion. We are a non-religious school accepting students of all faiths.

Our community is made up of people from many different religious backgrounds and heritages—Christians, Buddhists, Sikhs, Jews, Taoists and Muslims have all been or still are part of our diverse international community. In order for such a community to work and live well together, community members do not proselytize their faiths.

Delphian does offer a comparative religion course for seniors. This course deals with the major religions of the modern and ancient world and covers both the doctrine and practices that are found in Christianity, Hinduism, Confucianism, Buddhism, Islam and Judaism. Students read from the Old and New Testaments, the Koran, the Tao Te Ching, the Bhagavad Gita and from the writings of Siddhartha Gautama (Buddha) and Confucius, as well as other works.

If you don't teach Scientology, why do some people think you're a Scientology school?

Delphian School is a non-religious school that is not affiliated with any church. We think our school has become incorrectly associated with Scientology for several reasons:

1. We use the non-religious study methodology developed by L. Ron Hubbard. For this reason, many people associate the school with Mr. Hubbard, and since Mr. Hubbard is the founder of the religious philosophy known as Scientology (although not the founder of the Church of Scientology), Delphian has become incorrectly termed a "Scientology school" by some.

2. We welcome and encourage diversity of all kinds in our school community (we embrace free and open inquiry and the diverse perspectives of people of different backgrounds, religions and cultures). While we have staff members and students of all faiths represented at the school, many of our staff are Scientologists. We think this has encouraged some people to incorrectly assume Delphian is a "Scientology school." However, our community is made up of people from many different religious and cultural backgrounds. Because of our commitment to ensuring every person has the right to pursue their own faith, staff and students are asked not to proselytize their faiths to others.

3. Our educational approach is founded on the principles Mr. Hubbard uncovered in his many decades of research into the humanities. From his non-religious writings on education, morality, leadership, ethics, communication, organization and logic, we have developed courses that forward this knowledge and understanding to our students. This may be another contributing reason that some have incorrectly termed Delphian a "Scientology school."

Some of the aforementioned courses at the Upper School level include:

The Way to Happiness, a non-religious moral code involving 21 precepts for happy living.

The Ethics Book, an elementary approach to important concepts of ethics, morals and justice.

The Thinking Book, a basic course teaching students to differentiate logic from illogic.

Logic Series 1-3, advanced courses teaching students to critically evaluate data in order to resolve organizational problems and revert declining statistics.

Leadership, a senior level course covering basics of leadership and advanced communication skills.

Education, a junior level course covering important concepts for successful educational systems as well as elements of how to successfully educate self and others.

Professional Basics for an Artist, a course for those interested in the Arts, covering art as communication, professionalism, performance stage manners, etc.

Public Speaking, a senior level course including communication drills and outlines to become an effective public speaker.

Managing by Statistics, a junior level course covering statistics and how to read and manage by them.
