There have been 10 teachers in Cornwall suspended from schools for alleged improper relationships with pupils in the last three years.
The improper relationships all involved alleged sexual contact or behaviour between a teacher and a pupil.
Devon and Cornwall Police carried out investigations into all of the cases.
Figures released by Cornwall Council under the Freedom of Information Act showed there were four cases of alleged sexual contact or behaviour in the financial year 2010-11, three cases in 2011-12 and a further three in 2012-13.
In all of the cases the teacher suspected of improper behaviour was suspended.
The information, released following a request from BBC Newsbeat, does not reveal what the final outcome was following suspension.
Cornwall Council refused to say at which schools the alleged relationships took place or in which areas. The council insisted that any further information could lead to the identification of the staff or pupils involved.
Devon and Cornwall Police have so far declined to comment on what action was taken in each case.
