Crowds of concerned parents and residents had gathered outside the school gates as news of the brawl spread in the community.
There were initial unconfirmed reports of weapons having been seen and some parents then tried to scale the school fence to get into the grounds.
There were angry scenes outside the school as police officers arrived to try to restore calm.
Police dogs were deployed.
Teachers placed the school on lockdown after the initial fight and cancelled afternoon lessons to allow children to leave early.
South Yorkshire Police said one student suffered minor injuries and was treated at the scene.
Superintendent Shelley Hemsley, said: “We will of course be reviewing CCTV footage of the incident, and particularly of the crowds gathered outside of the school and any subsequent criminality which comes to light will be investigated.”
