The first tournament to be played will be the 2015 Torneo del Inca—played by the 17 teams in 3 groups. Subsequently, the Torneo Apertura will have all teams play each other once either home or away while the Torneo Clausura will repeat those matches but reversing the home or away ground. The winners of these three tournaments will advance to the semi-finals of the playoff phase at the end of the season granted they each finish at least eighth in the [|aggregate table] or above. The aggregate table will consist of the results of only the Torneo Apertura and Torneo Clausura. The fourth team to advance to the semi-finals will be the best placed team in the aggregate table that did not win any of the three tournaments.
Should one team win two of the three tournaments, they will automatically advance to the finals of the playoff phase and the semi-finals will be played by the team that won the remaining tournament and the best placed team on the aggregate table. Should one team win all three tournaments they will automatically become season champions. The aggregate table will also determine the three teams to be relegated at the end of the season.
The teams that qualify for the international competitions will be:
