The first two series brought us some household favourites. Who can forget Stephen Drew, the legendary deputy head of Passmores Academy in the first series, Educating Essex? Or stammering schoolboy Musharaf Asghar, who memorably overcame his affliction in a school assembly in the second series, Educating Yorkshire.
And this autumn Channel 4 is hoping to bring us more teacher/pupil stars in the eight-part Educating the East End, filmed at Frederick Bremer School in Walthamstow.
Here's an exclusive peak of the new trailer, which begins airing tonight.
Oh, and sit up straight, and no chewing while you're watching!
