A teacher could be kicked out of the profession after she admitted chatting up a pupil.

Catherine Rayne faces disciplinary action after she admitted sending a letter to a pupil asking if he wanted to be in a romantic relationship with her.

Colleagues at Michael Hall School in Forest Row had already warned her about her actions and the “expected professional boundaries” between herself and the unnamed student.

The string of incidents happened between September 2009 and March 2011.

Ms Rayne admitted she used texts, Facebook and letters to contact the boy.

She also sent gifts and inappropriate messages to him.

As early as the autumn termof 2009, Ms Rayne was given an informal warning regarding her inappropriate contact with pupils.

She was told that she should use the school email system for any contact that she had with her pupils. However, she disregarded that warning.

A report to the Teaching Agency disciplinary panel revealed how her amorous attentions made the pupil feel “uncomfortable” and that his relationships with his peers were affected because of them.

The boy’s father demanded the teacher did not contact his son again.

And Michael Hall’s chairwoman of upper school, Jo Reeves, warned the teacher, who had previously worked in Hong Kong, about her conduct and issued her with a formal letter.

But Ms Rayne continued in her pursuit of the boy.

In the end she resigned from her position but still sent another Facebook message and another present to the student.

The report from the Teaching Agency panel said: “By acting as she did, Ms Rayne demonstrated a serious lack of professional judgement that had the very real potential not only to damage her own professional reputation, but also the reputation of the school and the profession as a whole.

“The panel is satisfied that it amounted to conduct that might have brought the profession into disrepute.”

Ms Rayne had previously taught English and History in Hong Kong before gaining her diploma in teaching in Melbourne, Australia.

The panel will reveal its decision later this week.
