MR CHIPS, the Mad Hatter and the famous literary duo Sherlock Holmes and Dr Watson were among the colourful costumes as St Andrew's High celebrated World Book Day.
Head teacher David Matthews dressed as the titular character from James Hilton's novel Goodbye, Mr Chips.
His deputy Norman Revie donned the garb of Dr Watson and had his picture taken alongside Year 11 student Danielle Hughes, who was dressed as Sherlock Holmes.
Perhaps the most impressive costume was worn by head of drama Daniel Murphy, who came to the school in Warrington Road dressed as a Johnny Depp-inspired Mad Hatter from the film adaptation of Alice in Wonderland.
World Book Day, set up in 1995 by the UN's cultural and educational arm, is celebrated on the first Thursday of March. Half a million children in 21 countries took part last year.
St Andrew's pupils dressed as a variety of characters, including A. A. Milne's Tigger and Gandalf from The Hobbit and The Lord of the Rings saga.
"It was lovely to see so many students who already have a love for reading and today has been a wonderful opportunity to engage other students too," said Mr Revie.
"The pupils were really imaginative and diverse in their choice of characters."
