A teacher has been banned from the classroom after he sent messages to a sixth form pupil "enticing her to engage in a sexual act".
Benjamin Hutchins, 37, sent the messages to the student over Twitter and also contacted others on Facebook, while in his position as head of English.
He was also found guilty of unacceptable professional conduct for falsifying coursework.
Hutchins was banned from the classroom after the National College for Teaching and Leadership panel dubbed the teacher's behaviour "unacceptable".
He has the right to appeal to the High Court within 28 days.
The teacher at Melksham Oak Community School, Wiltshire., had been cautioned by Police for abusing a position of trust after sending a female pupil a private message on Twitter in January 2013.
The panel said because Hutchins had accepted a caution this "established a clear admission of guilt as to his conduct".
It described his "wholesale disregard" for the "integrity of the public examination system" by deliberately falsifying examination coursework and marks in English.
He was also found to be in breach of the school's code of conduct by contacting students via Facebook.
The panel said his behaviour was intentional and his engagement with students by social media had continued during his suspension while the school investigated his behaviour.
It said his behaviour was found to be "in clear breach of specific guidance he had received in writing from the head teacher".
The panel also ruled the seriousness of the allegations found proved against Hutchins meant he would "not be entitled to apply for restoration of his eligibility to teach".
