Schoolwide Curriculum Philosophy

As a Catholic international all-boys school, the curriculum at St. Mary’s reflects our Guiding Statements and a focus on the whole child, integrating the acquisition of knowledge, the establishment of responsible freedom, and the deepening of personal faith. Our standards based curriculum is developed using the Understanding by Design approach, guided by a Curriculum Review Cycle process for renewal, and examined for horizontal and vertical alignment in Grades RP-12 through mapping.

Students acquire the knowledge, skills, dispositions, and creative ability to move along the developmental arc from inquiry, to passion, to purpose. We seek to find the intersection between each student’s learning, their individual needs, and the needs of the world.

Students are made aware of global issues, as well as of the aspirations of people who work for peace, justice, freedom and truth, in the hope that these may engender beliefs and actions conducive to the betterment of humanity. In this process, personal development is marked by empathy and mutual trust.

Academic programs are rigorous and challenging and are designed to prepare students for higher education within a safe, caring and orderly atmosphere. The all-boy environment creates a place wherein positive self-esteem can fully develop and where learning is promoted at a pace appropriate for boys. A comprehensive and enriching co-curricular program is offered, which allows for individual expression to enhance self-worth.

At St. Mary’s, members of the international community in Japan can establish an identity respectful of both cultural and religious differences in an atmosphere that values diversity.
