World Book Day is an annual celebration of authors, books, and reading that takes place in over 100 countries. Testwood School celebrates World Book Day from March 3-7 by having English lessons focused on reading, a tutor group quiz with prizes, and participating in Oxfam's "message in a book" campaign where students write letters that will be included in donated books. The celebration highlights the importance of reading books to learn life lessons and make good choices.
