One former pupil from the 1980s is a familiar face at the school.
Mike Wallace started as headteacher at the junior school in September.
He said: "It is brilliant. I was talking to the children on Friday in assembly and showed them a photo from my year group and asked them which of the faces would be here today.
"They were all trying to guess famous people but it was me!"
The headteacher, who had been reminiscing with some friends from his school days, added: "This school becomes part of you."
Kath Schofield, a teacher at the school from 1971-85, remembered Mr Wallace as a 'delightful' pupil.
It was called Furze Platt County Junior School when it first opened in 1962.
