The Whitby High School in Ellesmere Port is taking part in the programme.
Assistant head teacher Kay Rimmer said the police involvement in the campaign helped the pupils understand the importance of consent.
“Students didn’t know, for example, that underage sexual assault is a sexual assault,” she said.
“They thought that it had to be somebody who was 18 or 19 and actually two 15 year olds in this kind of non consensual situation can have a police record.”
Data shows that more than 85% of the sexual offences were carried out by boys, Cheshire Constabulary said.
