It is claimed that children may be sent to boarding schools to give more opportunities than their family can provide. However, that involves spending significant parts of one's early life in what may be seen as a total institution and possibly experiencing social detachment, as suggested by social-psychologist Erving Goffman. This may involve long-term separation from one's parents and culture, leading to the experience of homesickness and may give rise to a phenomenon known as the 'TCK' or third culture kid.
Some modern philosophies of education, such as constructivism and new methods of music training for children including Orff Schulwerk and the Suzuki method, make the everyday interaction of the child and parent an integral part of training and education. The European Union-Canada project "Child Welfare Across Borders" (2003), an important international venture on child development, considers boarding schools as one form of permanent displacement of the child. This view reflects a new outlook towards education and child growth in the wake of more scientific understanding of the human brain and cognitive development.
Data have not yet been tabulated regarding the statistical ratio of boys to girls that matriculate boarding schools, the total number of children in a given population in boarding schools by country, the average age across populations when children are sent to boarding schools, and the average length of education (in years) for boarding school students.
