Like the Sorting Hat found in the Harry Potter series that place students, according to their characters, in one of the four houses, the real-life sorting hat would consist of counselors, on the advice of psychologists, accounts by student teachers, and individual students, help determine where the students belong in a "House", with final approval and advice by the child's guardian. The "House" is a multi-step process in the life of a child, and helps shape the child into what he will eventually become.
This process assumes that each person has the potential to be a leader or expert in his endeavors, if properly trained and fostered, according to the interests and natural talents of the individual. Advancements in personality psychology, as with the MBTI+ system, will help make this happen. This will create a more efficient job system, and helps ensure the right people are placed in key positions.
Each "House" will engage students' mentally, creatively, emotionally, and physically. Mentally in that they will learn all they could, emotionally in that they will be properly socialized with fellow students, and people of different backgrounds and cultures. Physically in that the students will be ensured of proper exercise, and nutrition, so that nobody is left behind. Creatively in that they will be trained in a skill like art or music.
The Houses can be:
Military and Politics - Physical Sciences (special focus on math, chemistry, physics)
Military and Politics - Humanities (special focus on psychology, culture, literature)
Economy and Politics - Physical Sciences (special focus on math, finance, economics)
Economy and Politics - Humanities (special focus on history, biology, language)
