In particular in less developed countries, schooling is often insufficient in content and quality, with overcrowded classrooms, teacher insufficiently trained and overworked, insufficient equipment and without the help of essential support services.
At least one third of existing schools and universities have poor facilities, especially in developing countries. A 1996 survey of facilities in higher education in the USA showed a total backlog of $32.5 billion, or which $7.1 billion is considered urgent.
