The members are elected via plurality-at-large voting: the province is divided into two districts, the first district sending three members, and the second district sending seven members to the provincial board; the number of candidates the electorate votes for and the number of winning candidates depends on the number of members their district sends. The vice governor is the ex officiopresiding officer, and only votes to break ties. The vice governor is elected via the plurality voting system province wide.
Aside from the regular members, the board also includes the provincial federation presidents of the Liga ng mga Barangay (ABC, from its old name "Association of Barangay Captains"), the Sangguniang Kabataan (SK, youth councils) and the Philippine Councilors League (PCL). South Cotabato's provincial board also has a reserved seat for its indigenous people (IPMR).
