A Snapshot of Addenbrooke Classical Academy

A Liberal Arts Education Using a Classical Framework


We practice the Trivium by incorporating teaching methods necessary for the grammar stage, the logic stage, and rhetoric stage, as well as the content traditionally found in each.


We offer and study arithmetic, geometry, music, and astronomy to gain an understanding of the integral nature of the universe.

Core Knowledge

The Core Knowledge scope and sequence, developed by E.D. Hirsch, is taught in grades kindergarten through eighth grade.

Charlotte Mason Principles

Using the Charlotte Mason methods of nature study, the study of habits, art and music, living books, narration and dictation, we seek to spark curiosity in students and inspire them to discover the pleasure of learning for its own sake.


Beginning in fifth grade, and intensifying in grades seven and eight, all students study Latin. Besides its modern use in the medical and scientific fields, this study is invaluable in learning grammar, parts of speech, vocabulary, and increasing the ability to write well.

The Good, True, and Beautiful

Everything we study at Addenbrooke Classical Academy, math, literature, music, history, the sciences, languages, and art rests on the foundation of discerning that which is good, true, and beautiful. We believe that ability to discern is what separates us from beasts and is worthy of lifelong study.
