The school qualified after being crowned BFC Community champions in January.
Unbeaten Briercliffe came into the competition on the back of nine straight wins, and advanced to the semi-finals after 3-0 and 2-1 wins and a 1-0 defeat.
In the semi-final, against their opponents from their second group match – the only team to beat Briercliffe so far this season, the game finished 1-1 after extra time, but Briercliffe scored all five of their penalties, taking them through to the final against St Peter’s Morecambe, which again went to penaltirs, where Briercliffe prevailed.
