The grand final for the Spotlight on Schools Talent Contest will see seven acts from four schools battle it out for the number one spot and a £500 prize.
Representing Blessed Trinity are Dance Academy, Drama Academy and dance duo Nadine Burgundo and Lauren Rowe while Katelyn Haydock and Jessica Brown will perform duets for Unity College and Denisa, Emily, Aqueela, Emilija and Jessie will take to the stage as Primet Academy's Star Dancers.
Tap dancer Tasha McSherry and singer/guitarist Hannah Smalley, both of St Christopher's CE High School, Accrington, will complete the line-up.
Organiser Molly Ralphson said: "The level of talent in the contest has been amazing. I really don't envy the judges having to decide the winner on Friday!"
Sponsors Standish Street Dental Practice have offered the £500 prize, which will go towards the winner's school. A panel of professional judges comprising Karen Metcalfe, Max Preston and Jon Hoyle will be on hand to pick the champion while a second prize-winner will be voted for by the audience.
The contest will take place on Friday at Burnley Youth Theatre, Queen's Park Road, at 7pm.
