Miss Hartman is the teacher in Jade and Drew's class in Jade's school. She never believed the outrageous stories Jade told in her classroom about the adventures she would have with her Uncle Jackie. Because of this and Jade's disruptive or rude behavior, Miss Hartman would either send Jade to detention or call Jackie. Despite this, Miss Hartman loves teaching and her class (even Jade). Seen mainly in the first two seasons and the fifth season where she was accidentally changed into a demon by Hsi Wu's chi (which was her most important appearance), Miss. Hartman had few appearances in the third and fourth seasons. After she got the demon Chi, she began to believe Jade's stories a little.
