In the Netflix series "Sex Education," the old school, Moordale Secondary, was thrown into jeopardy at the end of season three, thanks to the headmistress Hope Haddon (played by Jemina Kirke)
. The school was later closed down and sold to property developers
. The decision to move the students to a new school, Cavendish College, was made to provide a fresh start for them
. The transition to Cavendish College marks a significant change for the characters, including Otis Milburn (played by Asa Butterfield) and his best friend Eric Effiong (Ncuti Gatwa)
. The new school environment offers a culture shock for the Moordale students, who are accustomed to the old school's traditions and values
. The departure from Moordale also explains the absence of some characters, such as Olivia Hanan (Simone Ashley), Lily Iglehart (Tanya Reynolds), and Ola Nyman (Patricia Allison)
