I am a Professional Member of the Chartered Institute of Editing and Proofreading (CIEP). This is a professional UK-based organisation for editors and proofreaders that promotes excellence in English language editing (formerly called the Society for Editors and Proofreaders (SfEP)). I am proud to be a member of this organisation and abide by its code of practice:
The CIEP’s code of practice (CoP), Ensuring editorial excellence, is a really useful resource for editorial professionals. Its purpose is to ‘establish standards of best practice for CIEP members and help them maintain them and to encourage good professional relationships’.
The CIEP’s website introduces the CoP by saying that ‘Good communication between client/employer and freelance/employee is essential. Clear briefing and the agreement of terms are vital if high standards are to be maintained by both parties, and unsurprisingly they’re emphasised by the CoP.’
In addition, the CoP includes guidance on the professional behaviour of a freelance/employee and a client/employer and standards for proofreading, editing and project management. It also provides information on web editing, electronic file handling, email etiquette, confidentiality and computer security
Since the summer of 2016, I have been co-running the South Warwickshire and Coventry local CIEP group. You can download the code of practice here
