The Championship served as the second tier of Northern Irish football for this season.
Portadown were the champions, achieving promotion back to the top flight after only one season of absence.
The bottom 3 clubs (Tobermore United, Dergview and Killymoon Rangers) were relegated to the newly introduced Championship 2 for next season.
Members of the Interim League had one year to make improvements in order to gain entry to Championship 2 for next season.
10 of the 12 clubs managed to meet the criteria, along with Sport & Leisure Swifts and Knockbreda who both achieved intermediate status, with only Brantwood and Oxford United Stars failing to do so.
