Senior students and staff at Whanganui Girls' College celebrated the end of term on Friday by dressing up as superheroes.
Principal Tania King said it was a good opportunity for teachers to chill out with the students and have a laugh with them.
"It is really important. It's nice for all of the girls to understand that we're all human, we all like to have a laugh and that's what it's all about.
"We've had some fantastic leaders this year and we are celebrating them."
