Delphian School Photo #2 - Because our students study independently and learn from their materials instead of through a lecture-style classroom, each student in a class could be studying on a different course.
Delphian School Photo #3 - Not sure about learning on your own, without a teacher? Most people don't know there is an actual technology of study - ways to learn without memorization or memory tricks. We firmly believe that with the right study tools, a student can be his own best teacher. At Delphian, we'll show you how to become just that.
Delphian School Photo #4 - We believe education has to be personal. That's why Delphian students study on individual academic programs tailored to their interests. Making films, designing a computer game, helping to construct a bridge - their interests become part of their high school program.
Delphian School Photo #5 - Application of the subject being studied is central to learning. That's why Delphian students take what they're studying out into the world to apply it to their lives. By the time they graduate, Delphian students have spent over 1000 ours on practical activities - projects, internships, apprenticeships and personal interest activities.
Delphian School Photo #6 - No matter what science course they're studying, Delphian students spend the majority of their time in the lab or out in the world, putting scientific theories into practice, practicing the scientific method with their own theories, or putting proven theories into use.
Delphian School Photo #7 - The emphasis of Delphian's athletic program is on leadership, participation and sportsmanship. Delphian teams often win sportsmanship trophies from their league or tournament competition and are widely known for it. The school has many state-level competing teams every year.
Delphian School Photo #8 - When the academic day is over, our students participate in afternoon classes of their choosing - music, art, theater, athletics, game design, film, photography...on average 22 elective activities to choose from throughout the year.
Delphian School Photo #9 - We think of these as complimentary co-curriculars - not extra-curricular - because music, art, athletics and all the rest are all part of a well-rounded education.
Delphian School Photo #10 - Shouldn't your education be about you? Shouldn't it give you the freedom to explore areas you're interested in, to study subjects that are interesting and important to you? Visit and learn how to create your own education.
  • Located in Sheridan, Oregon, we are and independent and private day and boarding school for primary through high school students.
  • The Delphian School offers a demanding and groundbreaking independent-study program that focuses on the practical application of the subjects being studied.
  • Our student community is made up by a diverse mix of American and international students from more than 17 countries and various cultural and religious backgrounds.
  • At The Delphian School our academic philosophy focuses on using the information being studied, instead of memorizing the data just to pass an exam. Here, students learn how to evaluate the importance of the information they are studying by comparing it to other concepts they`ve already learned. In the end, the information they learned doesn`t just become another useless fact that they will memorize and then discard; it has become an integral part of their education as a whole. And, most importantly, during the process our students have learned to reason and think for themselves and are able to apply what they learned to their daily lives.
  • 87% of the students who graduate from the Delphian School are admitted to their first choice college. Our students constantly score 25% higher than the national average on the SAT.

School Notes

  • Delphian's History and ProgramDelphian was founded in 1976 by a group of educators concerned about the decline in the standards of American education. Delphian curriculum integrates innovative study methods recognized worldwide as a breakthrough in education. By learning how to study, without memorization or memory tricks, students develop the confidence and knowledge to tackle the most challenging subjects and learn anything on their own. They become their own best teacher.All Delphian students spend time putting their knowledge into practice. By the time they graduate, students have devoted over 1,000 hours to practical field activities, projects, and internships or apprenticeships.Rather than place or advance a child based on age or number of months spent in one grade level, Delphian takes the approach that each level of a student's education involves the acquisition and demonstration of particular abilities and knowledge. Spending exactly a year at one level may be fine for some children but not for others. Some students thrive at a faster pace, and some need more time. In fact, most students experience a little bit of both from month to month, depending on the subject matter, their age, or any number of variables.Delphian School utilizes the concept of forms instead of grades as a way of getting excellent learning results without forcing all students to move at exactly the same pace through the material. The School has a defined set of rigorous standards which must be met for a student to complete a form. Though forms can be roughly equivalent to grade levels and ages, it is possible for a younger student to move on to a higher form once they've met all the requirements for their current form. In this way, each student can get the full benefits from the curriculum and keep advancing as rapidly as he or she is maturing.At the beginning of each new form, students work one-on-one with a curriculum specialist to develop their own, individual program of academic study to agument the core curriculum. They work to fill in any gaps in their previous educations, bolster areas that may need extra attention, and follow their personal academic passions.Because of the independent study nature of our program, students can move as quickly through their courses and forms as they like, as long as they demonstrate that they understand and can apply the material. Student LifeDelphian's student body takes a highly active role in all school activities, giving each student the opportunity to learn personal lessons about responsibility, ethics, integrity, and leadership. Once academic classes are finished, our students jump into a variety of afternoon activities  sports, music, art, drama, photography and dozens more elective courses. In their evening downtime, Delphian students might get together with friends in the recreation room, work on their jump shots in the gym, participate in a choir sectional, get in some extra study time, or just relax in the dorm.Student Council members do much of the weekend activity planning, which might include heading off campus to catch a play, movie, or sporting event in Portland; take part in a community service activity; go ice skating or skiing, camping or shopping. On-campus events might include a nighttime game of Capture the Flag and a bonfire, a special dance, or Friday Night Performance, where students take the stage to sing, act, dance, or perform songs from their favorite bands.MatriculationDelphian School graduates are accepted at top ranked colleges and universities across the United States. 95% get accepted into their top choice colleges.
