The league was reduced from sixteen to twelve teams as a result of the league system in Northern Ireland being restructured by the
IFA. Five of
last season's sixteen Premier League teams failed to gain a place in the new twelve-team Premiership, and one new team -
Bangor - gained entry from the
IFA Intermediate League. Of the five teams who missed out, three -
Armagh City,
Larne and
Limavady United failed to obtain the necessary domestic licence.
Portadown obtained a licence, but was controversially excluded because a club official missed a deadline for submitting an application form by several minutes. Finally,
Donegal Celtic obtained a licence, but was ranked thirteenth in the entry list, and thus missed out by one place. ==Team overview==
