Portadown were promoted as champions of the 2023–24 NIFL Championship (returning to the top-flight after a one-season absence), replacing the 2023–24 NIFL Premiership bottom-placed team Newry City.
For the final five matches, the table splits into two halves, with the top six teams forming Section A and the bottom six teams forming Section B.
The play-offs are one-off matches, with the higher-ranked teams given home advantage and extra time and penalties used to determine the winner if necessary.
If the 2024–25 Irish Cup winners finish in the top three, the third-placed team will qualify automatically for the Conference League spot and the spot will be vacated.
If the Irish Cup winners finish in between fourth and seventh, that spot will be vacated.
