Boarding schools often create stronger friendships and alumni networks which last for a lifetime.
Children are kept at arm’s length from the parties, drinking and drugs that are sometimes more easily available to pupils at day schools.
Children benefit from additional non-classroom contact with teachers in the evening, as well as supervised homework, music practice time and other extra-curricular activities.
Students are kept occupied in the evening. There is less use of technology and students are often more social.
Students tend to be more independent and confident.
Since boarding schools charge more, they can afford to pay staff higher salaries and therefore employ more experienced teachers and other members of staff faculty.
For the same reason, facilities and resources are also often better than they are at day schools.
