St. Barbara Catholic School follows the course of instruction issued by the Office of Faith Formation in the Diocese of Orange, and that of the State of California. Scope and Sequence information found in the Teacher Manual governs daily learning.

The curriculum is centered around the individual student, focusing on the progress and the successful learning of grade and age appropriate subject matter. Differentiated instruction  through the use of learning centers, technology, levelled math and language arts classes, and where called for learning support, allows each student the opportunity to work and learn to their full potential.
