We Finally Know When ‘Sex Education’ Will End With Season 4

Class is back in session — if you’re a student at Moordale Secondary. The fourth and final season of Sex Education has finally come out with its first teaser, giving fans their first look at Otis, Eric, and the rest of the group as they embark on their first year at Cavendish Sixth Form College. With a brand new school and brand new friends, Sex Education fans can expect this season to have many different twists and turns. 

Creator Laurie Nunn commented on the ending of the show in a letter to the Sex Education fans, explaining that writing the final season felt “bittersweet” and “it was not an easy decision to make” for the writers. “As the themes and stories of the new season crystallized, it became clear that this was the right time to graduate,” Nunn stated on the Sex Education Instagram account. 

Even though the series is ending, fans have many questions on how the fourth and final season of Sex Education will be wrapped up. With a final release date and first teaser having been revealed on July 5, here’s everything we know about this season of Sex Education

When is Sex Education Season 4’s release date?

The fourth and final season of Sex Education will be released on September 21 on Netflix. 

What is going on in the Season 4 trailer of Sex Education?

The trailer shows Otis and Eric on their first day at Cavendish Sixth Form College. It’s clear that there will definitely be new characters joining the group, meaning more educational sessions from Otis. The trailer also teases that Otis is no longer an only child, as his mother has given birth. We’re also given glimpses into Maeve’s new life in the United States, Ruby and Otis connecting again, and Adam adjusting to his new university life. 

Who in the Sex Education cast is not returning for Season 4?

Sad news: Sex Education fans can expect a few fan favorites to not be returning to Season 4. Simone Ashley (Olivia), Tanya Reynolds (Lily), Patricia Allison (Ola), and Rakhee Thakrar (Ms. Sands) will not be returning this season to Sex Education

Ashley confirmed that she would not be in Season 4 of Sex Education in an interview with ITV’s This Morning, stating that she was “a Bridgerton girl now,” and is busy filming season 3 of the hit Netflix series. Reynolds told RadioTimes in an exclusive interview that she was leaving Sex Education, saying, “You have to let a few older characters go to make way for newer ones” and expressed how grateful she was to play a fan favorite character. Allison’s departure from the show was due to new project opportunities, and Thakrar also teased that she was working on a major project that prevented her from being in the fourth season.

It’s not entirely clear yet what everyone’s roles will be, but I can say that this season looks like it’s going to be packed with many different storylines.
