'Bad Education' is to return for a 10-year anniversary special and a spin-off series.
The comedy will head back to BBC Three for a 45-minute episode, which will see Jack Whitehall reprise his role as teacher Alfie Wickers, who will reunite with his old students at Abbey Grove for a chaotic careers day.
Jack said: "I'm so pumped for a ten-year anniversary special of 'Bad Education', the show that launched my career.
"I have such fond memories and it will be great for the fans to check in and find out what class K have been up to since they left and if Alfie Wickers is still as much of a melt as they remember."
A brand-new spin-off - which will air on BBC Three and BBC iPlayer - will see a new intake of unruly students at Abbey Grove and two former classmates, diva Stephen (Layton Williams) and soon-to-be-family-man-with-responsibilities Mitchell (Charlie Wernham) will find themselves on the other side of the desk as newly qualified teachers.
Jack added: "The new series is so exciting. I'm so old and irrelevant I've decided it's best I take more of a producer role with 'Bad Education', but we've assembled a young, talented group of writers led by the brilliant Nathan Bryon who will be carrying the torch.
"Charlie Wernham is his generation's Danny Dyer but with less royal heritage. Hopefully being a lead in this will be a springboard to him doing a decade of violent Brit flicks about hooliganism.
"Layton Williams is a superstar. I honestly think one day he will be an EGOTT (Emmy, Grammy, Oscar, Tony, TV Choice Award winner). Abbey Grove and the new class K couldn't be in safer hands."
Jon Petrie, Director of Comedy Commissioning at the BBC, added: "Jack being back on BBC Three dawns the start of a new term for 'Bad Education'.
"The original series helped launch the careers of many talented comic performers we see on TV today, and we hope the new series, written by some of the best young comedy writing talent in the UK, will unearth more gems for BBC comedy fans to enjoy."
