       There are students from all over the world at the United World School. In this school these

students study and spend their free time together. The school believes this will help them grow up

to be knowledgeable, caring and friendly.

       Once a year, there is a special "United Nations" show. Students are allowed to show anything

they want, but anything that comes from their traditional cultures. To get ready for the festival, they

have to teach each other.  And the school believes this will help them understand and enjoy the

culture of their friends better.

       This school also believes that students should be allowed to make some decisions themselves.

For example, the older students are allowed to wear what they want and the younger students are

allowed to choose which kind of uniform they want to wear. But all students are asked not to wear

an expensive necklace or something else like that,  and not to wear clothes that will make other

students unhappy.

       It is never possible to make everybody happy, but if we want to have a much more wonderful

world, it is important for students to understand and enjoy other cultures as well as to be proud of

their own.
