The value of the Dalek is not known but Ms Willey estimates that the replica could be worth hundreds of pounds.
"He's a little bit damaged here and there, but he's still got to be worth hundreds," she said.
"Someone out there must know where this Dalek has come from. And if the owner doesn't come forward, maybe we could give it to some charity or organisation that can do something with him."
The school contacted police but officers say they have received no reports of a missing or stolen Dalek.
Detective Constable Caroline Prince, of Exeter's burglary team, said she would be keen to hear from anyone who might know who the Dalek belongs to.
