Miss Constance Hardbroom (Miss Hecate Hardbroom in the 2017 series) is the deputy headmistress and potions teacher of Miss Cackle's Academy for Witches. Miss Hardbroom is Mildred Hubble's form mistress in first form and through various combinations of events continues to be Mildred's form mistress throughout her years at Cackle's Academy. HB, as the pupils call her for short, has the ability to vanish into thin air - and she can sneak around invisibly and spy on her pupils who always get caught when they are in mischief.



Miss Hardbroom grew up in a strict household; she never had a birthday cake, and was only given one birthday present, usually something useful like a spellbook.

Miss Hardbroom as a child


Miss Hardbroom has a beautiful, sleek black cat called Morgana.[2]Miss Hardbroom owned her magic broomstick for twenty-five years, until Mildred accidentally breaks it, when she jumps on Miss Hardbroom having mistaken her for an evil witch.[3]

1986 film

1998 TV Series

Miss Hardbroom is a representative of The Cauldron Club, and she was in the club herself at Weirdsister College. [4] The Cauldron Club is for high-achieving students to further their studies and interests.

Miss Hardbroom also attended Witch Training College, where Mistress Hecketty Broomhead was her personal tutor; she taught Miss Hardbroom "Everything she knows" (including how to appear from thin air). Miss Hardbroom encounters Mistess Broomhead twice at Cackle's, first as a Witches' Guild inspector, and then as acting Headmistress.

In her first year, Mildred saves Cackle's Academy from Agatha Cackle and her coven, earning her first smile from Miss Hardroom. In Mildred's second year, Mildred saves Miss Hardbroom's life after Miss Hardbroom slips over, is knocked unconscious, and inadvertently set adrift on a boat; Miss Hardbroom is grateful for this.

Two episodes in the TV series give particular insight into Miss Hardbroom's character: The Inspector Calls, and The Millennium Bug, both in season two. In The Inspector Calls, we meet Hecate Broomhead, and discover that Miss Hardbroom is afraid of her. In The Millennium Bug, Miss Hardbroom threatens to resign when Mr Hallow decides to sell the school- she can "only dance to one tune" and doesn't want to teach in the new school. This leads to a conversation between her and Mildred, who ends up saving the school.

Miss Hardbroom states that she "sleeps most nights, six hours at the weekend!"[5] She uses Wide-Awake Potion to keep herself going[6], and is often on the lookout for students sneaking around at night. Miss Hardbroom also owns a Magic Mirror, which is kept in the staffroom.[7]

Weirdsister College

When Mildred starts at Weirdsister College, Miss Hardbroom is summoned by magic to test Mildred (and tell her off), to see if she was strong enough to enter Weirdsister as a student. Mildred passed and Miss Hardbroom wished her luck, and a smile before returning to Cackle's.

The New Worst Witch

In The New Worst Witch, Miss Hardbroom dislikes Hettie and favours Belladonna and Cynthia. She now has disagreements with fellow teacher Miss Nightingale.

2017 TV Series

In CBBC's 2017 adaption, Miss Hardbroom believes that witchcraft is in decline. Because of this, she favours the talented Hallow sisters, Ethel and Esmerelda, and anticipates the termination of Mildred's trial at Cackle's. She claims that she does not hate Mildred; she simply believes the academy is "no place for [Mildred]".

Whilst she terrifies her students and is strict and severe, it is clear that she always acts in what she thinks is in the best interests of the academy. It is her who subtly double-crosses Agatha Cackle in the first episode by finding a loophole in the Witches' Code that Mildred can exploit.

Miss Hardbroom in the books

In Out of Bounds, when Agatha escapes her banishment, Miss Hardbroom puts protective enchantments on the castle, so that no one can get in unless they are invited, and students are banned from leaving the school grounds.

In The Worst Headmistress, Miss Hardbroom hints to Maud that Miss Cackle is trapped in the painting in the Headmistress' office. After the students are unable to rescue Miss Cackle, Miss Hardbroom tries to summon Miss Cackle herself, but her magic sets off the Agatha’s alarm, and Agatha traps Miss Hardbroom in the painting as well. When Agatha tries to destroy the school, All the students chant together to stop her spell, and this also changes Esmerelda Hallow, the teachers, and the grand wizard back into themselves, and Agatha and Miss Gullet end up trapped in a painting by Miss Cackle.

Physical Appearance

Miss Hardbroom is tall and thin with waist-length black hair which she keeps "scragged into such a tight knot that her forehead looked quite stretched". Miss Hardbroom keeps her hair tied up in a tight bun at all times, except for the Halloween celebrations, as it’s tradition that all the witches wear their hair out for Halloween. Mildred remarks that she doesn't look half as frightening when her hair is down. In the TV series she also wears her hair out at Miss Drill’s investiture and at night sometimes.

Miss Hardbroom usually wears predominantly black, ankle lengh, long sleeve dresses, though she has purple pyjamas. A notable exception is in the Christmas pantomime, when she plays the fairy godmother in Cinderella- she wears a white fairy dress, complete with white tights, wings, wand and a tiara.

In the 1998 TV series, Miss Hardbroom wears keys hanging at her waist. One of these keys opens the store-room near the Great Hall.

In the 2017 TV Series, Miss Hardbroom wears a pocket-watch on a chain around her neck and her nails are painted black.

Personality and Traits

Miss Hardbroom, as deputy head, is the real power behind the throne at Cackle´s. It is her who mostly succeeds in imposing her will on everybody by means of frowning, shouting or simply talking a blue streak till everyone gives in to her.

Miss Hardbroom is a stickler for standards and tradition, and believes in strong discipline. She is terrifying and extremely strict, and has been described as reducing any pupil to a gibbering heap with just one word. It is her who gives Mildred the infamous title of "the worst witch in the school". Miss Hardbroom is a “staunch traditionalist” ; Her life is run by tradition and she thinks computers (and all other moder technology) are infernal machines, as seen in "Sorcery and Chips".

However, Miss Hardbroom has been shown to have a kinder side to her. In fact, Mildred once remarked "You know, sometimes I don't think she’s as bad as we think she is". Miss Hardbroom's softer side does come through on occasions, such such as her thanking Mildred for saving the academy from Miss Cackle's evil twin sister, Agatha Cackle, at the end of The Worst Witch, her accident in The Worst Witch All at Sea and the restoring of Mildred's hair to its rightful length in The Worst Witch Saves the Day.

Miss Hardbroom can be quite immature when upset, this is shown by her temper tantrums in The Millennium Bug (mentioned only) and Better Dead Than Co-ed. HB talks very loudly when she's getting angry or upset, and she will disapear to be by herself-at least until Miss Cackle or Mildred find her.

Despite Miss Hardbroom

's fearsome nature, it was hinted at that she was actually afraid of at least one witch; that being Mistress Hecate Broomhead, her old personal tutor, whom Hardbroom claims to have taught her "everything she knows".

Abilities and Skills

Miss Hardbroom is an exceptionally talented and powerful witch, and it is often left up to her to save the day when situations get out of hand. When Miss Cackle's evil sister Agatha and her sidekicks try to take over the school, Agatha states that "Hardbroom is the really dangerous one" and must be dealt with first, suggesting Hardbroom is well-known and feared by the adult witch community.

Her most notable ability is the ability to appear from thin air, and was the only witch (aside from Hecate Broomhead) who was shown on the show to possess this ability. She took the entire cohort of Mildred's year to the great hall via this method in A Mean Halloween. Hence, the students often say that one never knew if she is truly gone, or if she was still there in an invisible state. In the first episode of The New Worst Witch, Mildred Hubble was shown to possess this ability, indicating that she had either learned it at Weirdsister College, or was taught it by Miss Hardbroom. Miss Hardbroom's primary method of casting spells was through her fingers: pointing with the index and little fingers.

When Miss Cackle's evil sister, Agatha, and her sidekicks try to take over the school, Agatha states that "Hardbroom is the really dangerous one" and must be dealt with first, suggesting Hardbroom is well-known and feared by the adult witch community.

Miss Hardbroom gets "the best results of virtually every potion teacher in the country".


Miss Cackle

Miss Hardbroom is good friends with Miss Cackle. She dislikes most of the other teachers, particularly Miss Bat, who she sees as incompetent and irresponsible. She feels Miss Drill and Miss Cackle are too soft on the girls.

Miss Hardbroom has a close relationship with her Headmistress, Miss Cackle. They are close friends and have almost a mother-daughter sort of relationship. In Mildred’s second year, Miss Cackle suggests that Miss Hardbroom is overworking herself and needs a holiday; this leads to Miss Harbroom coming on the second year’s trip to Rowan-Webb’s riverside home.

When Mr Hallow wanted to sell the Castle to Amanda Honeydew, and Miss Hardbroom threatens to resign in protest, Miss Cackle was seen chasing her down the hall, begging her to reconsider. When Miss Cackle and Grand Wizard Hellibore were planning to merge Cackle's with Camelot College into a single, co-educational school, Miss Hardbroom gets upset. Miss Cackle finds her sitting by the river, and talks to her.

Miss Pentangle

In The Worst Witch Saves the Day, it is revealed that Miss Hardbroom is good friends with Miss Pentangle (they especially like playing chess together). [8]

In the 2017 TV Series, Miss Hardbroom and Miss Pentangle used to be friends, and it is implied that they went to school together. Miss Pentangle was popular in school, while Miss Hardbroom was tall, gangly, and not as popular. Miss Hardbroom thought Miss Pentangle wouldn’t want to be friends with someone like her, but Miss Pentangle actually considered Miss Hardbroom her best friend. They eventually make up thanks to Mildred.


Miss Hardbroom hosts a strong contempt for every creature of the male species. when "The Witchy Hour" radio show was hosted at Cackles', DJ Icy Stevens seemed to fall in love with her at first sight, and she appeared to reciprocate, but she simply appreciated his admiration. When he invited her to go away on a romantic holiday and put his hand on her arm, she immediately rebuffed him. She does show a level of respect for both Mr Blossoms however.

Mildred Hubble

Miss Hardbroom took a particular disliking to Mildred at first sight - It is Miss Hardbroom who gives Mildred the title of "the worst witch in the school." This used to be quite mutual. However, getting acquainted with each other and actually saving each other´s life now and then, both grudgingly had to learn (though not to admit) that each of them has her strong points - which results in a kind of love-hate relationship. Still, Miss Hardbroom relishes in yelling at Mildred and her friends and approving smiles are very thin on the ground with her. Miss Hardbroom frequently praises and rewards Ethel Hallow, and frequently rebukes Mildred in front of the other students.

In the episode "The Millennium Bug" she and Mildred actually have a heart-to-heart conversation and in the episode "The Uninvited" Miss Hardbroom shows obvious signs of liking Mildred after Mildred saved her life from The Uninvited (the witch from Sleeping Beauty who put everyone into an eternal sleep by spraying them with cobwebs) by looking impressed at Mildred's ability to turn drawings into real people and by sticking Mildred and Jadu's expulsion letters to Ethel's fingers.
