There was seven participating teams in the 2016 Under-21 Provincial Championship. These teams played each other once over the course of the season, either at home or away. Teams received four points for a win and two points for a draw. Bonus points were awarded to teams that scored four or more tries in a game, as well as to teams that lost a match by seven points or less. Teams were ranked by log points, then points difference (points scored less points conceded). The top four teams qualified for the title play-off semi-finals. The team that finished first had home advantage against the team that finished fourth, while the team that finished second had home advantage against the team that finished third. The final was played as a curtain raiser for the
2016 Currie Cup Premier Division final. ==Teams==
