The NWOSPC is a series of member-only junior pig shows held annually between December and February. Only members of the NWOSPC can show in NWOSPC shows; membership is open to any student in the 12th grade or under who resides in a Northwest Oklahoma FFA school district or is enrolled in a Northwest Oklahoma FFA school district.
Each year, the show circuit features five to six shows. About half of the shows are single-day shows (on Saturdays), and about half are double-headers (Saturday and Sunday).
Exhibitors also earn points for their participation and placings at each show and awards are given to high-point earners at the completion of the circuit. These end-of-the-year awards are supported by sponsors.
