* NightmareFuel: ''The Genius of the Lamp'', in which Sybill creates a magic lamp from a torch, which begins to draw energy from everything around it, almost destroying the school.
* OlderThanTheyThink: An isolated medieval castle containing a magic school, with a forest nearby? A protagonist who has no prior knowledge of the magical world? A rival who comes from a leading magical family? A hook-nosed Potions teacher who favours the rival and despises the protagonist? A kindly, grey-haired Head who befriends and helps the protagonist? Classes in Charms and broomstick riding? While both ''The Worst Witch'' and ''Harry Potter'' clearly have very similar elements, Jill Murphy's series predates the latter by 23 years, with the first book being published in 1974.
