Deffry Vale High School

Deffry Vale High School was a high school located in Deffrey Vale, London, England.

It was infiltrated by the Krillitanes and was brought to the attention of Sarah Jane Smith and Mickey Smith separately. The Doctor and Rose Tyler were undercover in this school during the final stages of the Krillitane's plans, thanks to Mickey.

The school was destroyed in early 2007 when K-9 destroyed a vat of Krillitane oil. (DW: School Reunion)
