Police are investigating after indecent material was sent to girls at a Nottinghamshire high school via the internet.
Seven pupils at the West Bridgford School were sent messages and pictures at home from a social networking site.
They have been interviewed by police with a parent present.
The school's head teacher Rob McDonough said he was relieved that the pupils had been taught about internet safety and felt confident to report it.
He said: "I'm absolutely delighted that our girls recognised the dangers of what was involved and what they were potentially being drawn into and we've obviously done a lot of work in school, in talking to our children through assemblies and lessons.
"So they did spot this and I was delighted that they came into school and reported this."
A woman police officer interviewed the girls at the school in front of one of their parents who chose to be present.
