About Seisen International School
Seisen International School is first and foremost a Catholic international school. Our Guiding Statements are key drivers in all aspects of life in Seisen International School and are responsive to the nature of the community. While having a Catholic Christian foundation, our Guiding Statements are considered to be universal in purpose and intent. They echo our holistic approach to education both academic and moral, and they are deemed appropriate for our diverse representations of learners, nationalities, cultures, identities and faith communities in our school community. Seisen educates future world citizens to become men and women for others and with others, in the spirit of Jesus Christ. Seisen’s mission is to provide a safe environment with a focus on the multi-faceted nature of community wellbeing. We seek to empower each student, through shared responsibility, creativity, and human interdependence, to develop their unique talents and to become competent and compassionate players
