School Notes:

  • At Delphian, you won’t find teachers lecturing while students rotely take notes. You will find students actively engaged in learning, studying independently and moving at the speed that is right for them. You’ll see lively one-on-one and small group discussions on works of literature, art, business, science or current events. You’ll see students creating clay models to explain and demonstrate a concept. A student giving a presentation on his apprenticeship experience or a topic he’s just researched. And students heading to the science lab or out into the world to test or explore a theory. The Delphi Program is designed to help students relate what they’re learning to how they will use this information to succeed in life, and you’ll find our students living their education from the moment they walk into our school.  Our faculty excel at keeping students motivated and on track with their studies, and you can be assured that each student receives highly personal attention—every academic program isindividually designed to best cater to the student's academic needs and interests. Each student at Delphian is treated as an individual, and we seek to help all of them find their own purpose and use for their education.

School Reviews

As a parent, it''s so important to me to be able to have direct access to my children''s teachers and that they are willing and interested in communicating with me about my child. I get this in spades at Delphian. The teachers are wonderful and very interested in each individual child''s future. I so appreciate that.
