The exact number of members shall be determined by the board of county supervisors. Each member shall be appointed for a term of four years, provided that initial appointments may be for such terms as will stagger the expiration of terms and that appointments to fill vacancies other than by expiration of term shall be for the unexpired term.

B. It is further provided that those counties having a county board form of government as contained in Chapter 4 (§ 15.2-400 et seq.) of Title 15.2 shall select their school board as provided in § 15.2-410, as amended.
