CAL History Series
We're proud to offer the CAL History Series each year, featuring in-depth lectures on significant events and topics in world and American history for interested adults. This program grew out of a consistent request from parents and adults desiring a similar education to what we’re offering their children. After hearing about our classical curriculum, they would often leave a school tour asking, “Where can I sign up?” So this series is a sampling of what we teach in the classroom but we’re taking a deeper dive
for our more seasoned students.

Upcoming CAL History Series Lectures
Delve into the intriguing history of the Supreme Court, a branch of government that is often the least understood and defined in terms of its powers. Despite this, the Supreme Court has made significant rulings on critical issues such as religion, firearms, intimacy, and the family, affecting the core freedoms of American citizens. This thought-provoking lecture will explore how the Supreme Court came to be such a powerful institution, and what the future holds for the only branch of government with unelected members whose decisions cannot be countermanded without a constitutional amendment. Don't miss this opportunity to gain a deeper understanding of the Supreme Court's impact on our society!
