Why Choose
Chuo International School?
At CIS, education goes beyond academics—we nurture the whole child through our Montessori+ and Cambridge-certified curriculum. Students develop strong academic foundations, communication skills, and global awareness in a caring, fully English environment with small class sizes and expert teachers.
Our curriculum helps students develop:
Strong academic foundations in literacy, numeracy, and science
Communication, critical thinking, and problem-solving skills
Cultural understanding and global citizenship
Independence, leadership, and responsibility


Education is a natural process carried out by the child and is not acquired by listening to words but by experiences in the environment.
