Ms Marshall, who has performed with Tauranga Musical Theatre and directed her school's Stage Challenge entry this year, was unsuccessful with her audition for Toi Whakaari, the New Zealand Drama School, but intends to take a gap year and try again.
She is studying for NCEA Level 3 drama and will also sit a drama Scholarship exam.
"I love the storytelling aspect of the shows I've seen," says Ms Marshall, who has theatre performance as her goal.
Festival director Jo Bond is pleased to offer the students the chance to review.
"The festival is proud to be a good citizen of this community," she said.
"We're delighted to help support our teenagers achieve in the performing arts, whatever they choose to do in the future."
