A head teacher or school principal (also known as headteacher, headmaster, headmistress or the head, sometimes informally in Scots, the heidie or heedie) is the most senior teacher, leader and manager of a school. In the past, the headmaster or headmistress of a British private school was often the owner of the school or a member of the owning family, and the position often remained in the family for many generations. The school year in Japan begins in April and classes are held from Monday to either Friday or Saturday, depending on the school. The school year consists of two or three terms, which are separated by short holidays in spring and winter, and a six week long summer break.
