Female pupils say they have been left "humiliated" over enforcement of a uniform policy at a Merseyside school.
Girls have been made to enter Rainford High School in St Helens separately to boys and have had their skirt length inspected by male teachers, they claim.
Hundreds of pupils staged a protest against how rules, which have left some pupils in tears, have been imposed.
The school said "the implementation of the uniform policy was carried about by staff, both male and female".
More than 1,000 people have signed a petition against the policy with some calling it "outdated" and "ridiculous".
Tony, a parent who has complained about the treatment of his daughter, said: "When pupils returned after half term, they lined girls up and examined their skirts and told them, 'Yours is suitable, yours is not'.
