Over the last three years more than 5,500 alleged sex crimes in UK schools were reported to police, according to figures obtained by the BBC in September.
The figures also show that there have been over 4,000 alleged physical sexual assaults, and more than 600 rapes in UK schools.
A different study, Girlguiding's Girls' Attitude Survey 2013, found that 60% of girls in the UK between the ages of 13 and 21 have reported sexual harassment at school or college.
The report also showed that 51% have been subjected to sexual jokes or taunts, and that 1 in 3 girls aged between 16 and 18 say they have experienced unwanted sexual touching at school.
It's in response to these figures that Plan UK has now launched its campaign – Learn Without Fear.
The campaign, which began in September, is a branch of the charity's long-running project called "Because I am a Girl", which aims to work with governments around the world in the fight for girls' rights.
Lucy Russell, the head of UK girls' rights campaigns at Plan UK, told BuzzFeed News that sexual violence and sexual harassment in UK schools is just one of the important issues that the campaign aims to tackle.
"Gender-based discrimination is still happening in schools and is something that the government needs to address," she said.
Russell said Learn Without Fear takes a "youth-driven approach".
She said that the charity has spoken to young people about their experience of violence in schools, and now plans to ask them what they think the best solutions might be.
In addition to this, the campaign aims to work with governments to help implement programmes preventing gender-based violence at school, and ensure that all girls have access to safe, quality education.
The charity has also released the video to highlight the 246 million children thought to be affected by violence at school around the world each year.
"School should be a safe place, but for millions of girls worldwide, that's not the case," Tanya Barron, Plan UK's CEO, said.
"We're calling on the public to help us raise awareness of violence in and around school, and to support our work around the world to tackle the attitudes that allow such violence to occur. Help us ensure that every girl can learn without fear."
