Twenty teams participated in the promotion play-off. Each of the five groups of the Segunda División RFEF are represented by the four teams that finished the regular season between the second and fifth positions.[1] In the draw for the first stage, the participating teams were assigned to pots corresponding to their final regular season position. While avoiding matches between teams from the same regular season group, second-place finishers were drawn against fifth-place finishers while teams that finished third would play teams that finished fourth. The same draw process was repeated, to the extent that it would be possible, in the draw for the second round.[2]
The five winning clubs of the second stage attained promotion to Primera RFEF and accompanied the five group champions who had already achieved their promotion.[3]
The final two relegation spots (of 27 total) were also determined via play-offs. The four 13th-place finishers with the lowest point totals were drawn into two single-leg matches, with the winners securing survival in the Segunda División RFEF and the losers being relegated to the Tercera División RFEF. The two match-ups were selected through a random draw and hosted at a venue chosen from among the stadiums selected to host the promotion play-offs.
