Source: Soccerway A separate table is kept to determine the teams that are relegated to the Categoría Primera B for the next season.
For purposes of elaborating the table, Atlético Huila and Deportes Quindío, who were promoted from Primera B at the end of the first half of the season, were given the same point and goal tallies as the team in the 18th position at the start of the Finalización tournament (Deportivo Pereira).
As an exceptional measure for this season, and due to promotion and relegation being implemented halfway into the season, the two teams promoted for the Torneo Finalización (Atlético Huila and Deportes Quindío) entered with the same matches, points, and goals as the team in 19th place in this table at the end of the Apertura tournament (Alianza Petrolera).
