About Sex Education

Sex Education follows Otis Milburn running a secret school clinic with Maeve Wiley while his mum Jean writes about the same topics at home. Season 1 from 2019 sets Moordale rules, season 2 from 2020 widens to parents and panic, season 3 from 2021 brings a new head and protest, and season 4 from 2023 moves most of the group to Cavendish College.

Watch in broadcast order across the four seasons. Relationships and school policy stack year to year, so skipping breaks the payoff. The show ended as planned with season 4, and no revival has been ordered.

Good to know

Each season runs 8 episodes, 32 in total, with the last season acting as a soft reboot of setting but not of continuity. Moordale closure lands harder if you have seen the first three years. The tone stays frank but warm throughout, with school plots resetting each term while friendships carry forward.
