Petra Academy is the largest and oldest classical school in Montana, serving the Bozeman community and greater Gallatin Valle ... y with quality education students ages PreK through 12th grade. Petra Academy is a cross-denominational Christian school. All of our board members as well as our administrative staff and faculty ascribe to the historic creeds of the Christian Faith. We acknowledge Jesus Christ as both source and goal of all creation and history, and the center of any discussion of truth, beauty, and goodness. That said, ours is an open enrollment, meaning we do not require profession of faith from student or parent(s) to be considered for admission. Petra Academy is a member in good standing and accredited by the Association of Classical and Christian Schools, “organized for the mission of promoting, establishing, and equipping member schools committed to a classical approach to education in the light of a Christian worldview grounded in the Old and New Testament Scriptures, commonly known as the Bible.” ACCS offers an extensive array of services and provides accountability through accreditation. read more
