Although series creator Patrick Ness had already said he wouldn't be writing any more episodes, there had been no official announcement about the drama's future. But asked whether Class would be returning for a second season, BBC Three Controller Damian Kavanagh told Radio Times, "No, no."

“There was nothing wrong with it,” he said. “I thought Patrick did a great job, he explored an amazing world. In honesty it didn’t really land for us on BBC Three. Some shows don’t and I have to make decisions about what we’re going to do from a drama point of view, and what we did after Class was Clique, which worked really well for us.”

Set at the fictional Coal Hill Academy, a longtime recurring location of the Doctor Who universe, Class centered on its students and staff, combining the drama of school life with the horrors of time travel. Peter Capaldi’s Doctor guest-starred on the premiere episode to explain to the the characters their importance in protecting Earth from a tear in the universe at the school.

Doctor Who is gearing up for the arrival of the first female Doctor, with Jodie Whittaker to succeed Capaldi, who will end his run with this year's Christmas special "Twice Upon a Time."
