 After each Clausura, the two teams with the lowest points-per-game total for the previous six tournaments (three years, counting only Primera División games) were relegated to Primera B Nacional to be replaced by that league's champion and runner-up teams; the two teams immediately above contested promotion/relegation series with the third and fourth places in Primera B Nacional, counted by its aggregate table.In Primera B Nacional, the same procedure continues in use for relegation to either Primera B Metropolitana or Torneo Argentino A for non-Buenos Aires clubs.From 2015 onward, relegation from the Primera División will be based solely on league position at the end of the season (which, effective in 2016–17, changed from a February–December format to an August–June format).
