The survey of 3,229 members was carried out in September and October this year.
* Just under three quarters (74%) of members believe the public are concerned about members' conduct
* Under a third (31%) of members believe standards of behaviour have improved over the past two years
'We believe members don't want their reputations tarnished by the questionable behaviour of a minority,' said The Standards Board for England chair, Anthony Holland.
'We believe we are beginning to have an impact as it becomes clear what is, and is not, acceptable.
'We are also beginning to see sanctions imposed in cases where there has been a serious breach of the code. The recent casein which councillor Michael Perrin of Immingham Town Council was banned for three years after sexually harassing his town clerk is a good example of the effect we are having,' Sir Anthony said.
