A student in Canada has been told she could not sit an exam after she refused to partially remove her hijab.
The girl was asked by a male biology teacher to pull her headscarf behind her ears so he could see if she was wearing headphones, according to a spokesperson for the school in Montreal.
"She didn't want to show him her ears," Line Legare, from the College de Maisonneuve.
According to Ms Legare, the student said the teacher could touch her hijab to prove she was not wearing headphones, but that "made the teacher uncomfortable".
Following the exchange, the biology teacher told the girl she would not be able to sit an exam that day.
The teacher had a policy whereby he asked all students to prove they were not using headphones to cheat by showing him their ears.
No official complaint by the student has been filed yet.
The school is negotiating another time for the girl to sit the biology test.
Quebec Premier Philippe Couillard was asked about the incident and defended the teacher's actions.
He added that a bill regarding religious accommodation put forward by his government would give Canadians the chance to debate such issues.
