Owlsmoor Primary in Sandhurst will have the height of the fence around the school increased after The Circle Trust applied earlier this year to raise it by 400 metres to stop people from looking into a playground.
"This poses a security and safeguarding risk for the students that urgently needs to be addressed."
A small area of the play area will also be reprovided to fill in a steep slope.
The plan, application reference PA/2026/0647, was approved by Bracknell Forest Council on August 11.
