Oklahoma Virtual Preparatory Academy features the world-renowned Calvert homeschool curriculum, which is research-based and evaluated continually to meet national and state standards. Our comprehensive placement process determines the best curriculum option for your child.

A Comprehensive, Solid Foundation

The Calvert curricula is built on a rich foundation of reading, writing, and arithmetic. That foundation is then layered with history, science, music, geography, and the arts to ensure no gaps in instruction.

Calvert’s time-tested curriculum is built on the principle of subject integration. For instance, Calvert Fifth Grade students study the Civil War in history. At the same time, they also interpret Walt Whitman’s poem “O Captain! My Captain!” about Abraham Lincoln’s assassination and draft a composition entitled “A Civil War Battle.” This reinforced study across subject areas develops higher order thinking skills and promotes content mastery.
