Study the Quadrivium in the Classical Liberal Arts Academy

In 2021, we are making all of our curriculum content–over 100 courses–available for free. Between March and August, these curriculum pages will be filling out as we transfer the courses and lessons. Thank you for your patience.


In the Quadrivium, students study the four mathematical arts of Arithmetic, Geometry, Music and Astronomy.  Here, they learn the four parts of the science of Quantity.  Assessment in all courses below consists of challenging online examinations, for which perfect scores must be earned before students are promoted.  Written assignment grading and live assessments are available from Mr. Michael for all courses below.  See the “Academic Services” page for more information.
