Parents have until the deadline of October 31 to apply for a place for their child to start secondary school in September 2022.
They should already have been sent information about how to apply but full details are available on the Sheffield City Council website.
The latest figures show that for autumn 2021, a total of 13 schools across Sheffield were oversubscribed, with 200 children being turned away at one and youngsters in some cases being refused a place at the school their brothers or sisters already attend.
