"Student A found the increasingly intense communication from the [teacher] difficult to cope with, and asked her parents to intervene.
"Despite being asked to desist by Student A's parents, the [teacher] continued to send her text messages of an intense and personal nature."
Text messages were also sent to the girl's parents late at night. The content of the text messages to the student and her parents were not revealed in the decision.
However, the teacher admitted she had engaged in communication which was inappropriate, and that she had turned to the girl for support when she should have sought professional help.
She accepted she had "inappropriately burdened herself" onto the pupil and her family.
The woman was struggling with depression and anxiety at the time, the disciplinary tribunal was told, which she blamed on overwork.
Her lawyer said she had since developed a set of coping strategies and a support network that would minimise the risk of repeat behaviour.
It was noted that the emotional attachment was not sexual in nature.
The disciplinary tribunal ruled the teacher's behaviour amounted to serious misconduct, and that it "adversely affected the wellbeing of one or more students and reflects adversely on her fitness to teach". It censured her, removed her from the teaching register and ordered that her behaviour was recorded on her file.
