Mission & Values

  • About CGK

    The following is an introduction to CGK's educational curriculum and the faculty and staff who support it. Childcare and education are not mechanical manifestations of the policies of an organization, but rather, a reflection the passion and enthusiasm of all staff members involved.

    We hope that this section will help parents and others to understand the quality of childcare and education that comes from CGK's policies combined with the diverse backgrounds of its staff.

  • 12+3-Year Continuum Education

    Continuum education from 3-years-old until high school graduation. Continuity in our activities allows us to focus on education that is truly important for the future of the students, without wasting time on boring, repetitive studying.


  • IB Education

    The International Baccalaureate (IB) Education is an all-round education to develop internationally-minded individuals. Through IB education, we provide a consistent educational program from preschool onward.
