Calvary Christian School

Welcome to the New Website for Calvary Christian School

Calvary Christian School (as we were originally called) was founded in 1987 as a ministry of Calvary Apostolic Church of Concord.  Since that time, we have endeavored to work with families to provide a well-rounded education for their children in a Christian environment.  Each teacher is dedicated to the success of every student in their charge.  Whether in academics, emotional, or spiritual growth, we have a reputation for quality.
