Overview

Mission

At Delphian School, we prepare students for life by helping them master their academics and gain the skills and abilities they need to go anywhere.

What it reported doing in 2024

Delphi schools inc is a 501(c)(3) non-profit that has two primary activities in fulfilling its educational mission: the delphian school, a premier day and boarding school, and heron books, a developer and publisher of cutting-edge prek-12 curriculum. Both are located on a spacious and beautiful campus in the willamette valley of Oregon, the heartland of the pacific northwest. Delphian school services students of all ages within a prek-12 day and boarding program. As the founding school of a network of schools using the delphi program, delphian provides a model example of how the delphi program can be applied and the high standards that are achievable with this new, cutting-edge approach to education. Delphian has been preparing students for life and higher education through its rigorous school-year and summer programs for over 40 years. With an international student body, a 700-acre campus and a 24-7 learning environment it's a uniquely challenging and rewarding place for a young person to establish career goals and tackle them head-on. Delphian is known for two things: a) cultivating capable graduates who are prepared for whatever is next and b) assisting visiting educators and school leaders who seek to modernize their approach to education. Heron books provides a full spectrum of curriculum services and materials, including books, courses and educational resources for individuals, home-schoolers, and private schools. Heron's largest service is a personalized, integrated and full prek-12 curriculum package called the delphi program, used by a growing number of schools across the country. The delphi program has received national and international attention since its emergence on the educational scene in 1976 as the first personalized, ability-based program to achieve high standards while supporting students of all ages and educational backgrounds. Heron books is also known for providing unique study materials that specifically train students of all ages to study effectively and learn independently.
