The national championship was divided into two tournaments; the Torneo Regional and Torneo Descentralizado.

Each group had its teams advance to the Liguilla Regional, the Torneo Descentralizado and the División Intermedia. The Liguilla Regional determined the Regional champion. The Descentralizado divided the teams in three groups and the top two in each group advanced to the Descentralizado Liguilla which decided the Descentralizado champion.
