Staff at Stromness Academy are appealing to local families to check their bookshelves at home - to see if there are any school books lurking there.
The school are missing a significant amount of their book stock - with one particular maths textbook seeing significantly depleted stocks.
One hundred 'Maths National 5' textbooks were purchased in 2016 - with 25 of these having not been returned to the school over those two years - at £20 a book.
Any school books found at home can be returned to the school over the holiday period as part of a book amnesty.
Graeme Horne is the Acting Business Manager at Stromness Academy. He said: "The school has found that there's been a significant depletion of our book stocks across all departments and in the library too - and we'd really like to see these books back in the school for our current pupils to use and enjoy.
"We'd like folk to take a look around their homes - even if their children left school some time ago - and see if they do have any Stromness Academy books. usually it’s a result of pupils forgetting to return a book or putting the return off. Even if each family finds they have just one book, then the returning of all of these could make such a huge difference to the school."
