The Bahá'í summer schools were originated in America to meet
the requirements of the friends. They have been adopted by other Bahá'í
Communities the world over, but there is no reason why they should be called
"summer schools". There is nothing rigid about the term, it is purely
descriptive. The Guardian feels that although you can have the immediate
affairs of your summer schools managed by a convenient Local Assembly, they
should remain under the direct supervision of the National Spiritual Assembly
as they are national in character and not purely local.

December 1941 written on behalf of Shoghi Effendi to the National Spiritual
Assembly of Australia and New Zealand)
