About the CIEP

The Chartered Institute of Editing and Proofreading (CIEP) promotes excellence in English language editing.

We provide training and an online Directory of Editorial Services. We regularly publish resources for our members and those interested in editing and proofreading. Our members have access to a wide range of benefits, including a number of popular member-only forums, a growing archive of the Institute's collective wisdom and experience.

We have around 3,000 members in the UK and beyond, with a growing international membership. Our members work for a wide range of clients and employers – publishers, businesses, government and other organisations, academic institutions and authors. We formed in 1988 and were known as the Society for Editors and Proofreaders before being awarded our Royal Charter in 2019.
