On Monday, March 05, 2012, Katharine O’Moore-Klopf published a blog entry that discusses how editors can improve their skills on her EditorMom Blog. You can find that blog post in its entirety at http://editor-mom.blogspot.com/2012/03/how-do-you-know-when-you-know-enough.html
I have posted the beginning paragraph to that blog post with her consent here. I highly recommend that you read the entire post. It’s well worth your time.
How Do You Know When You Know Enough?
“There are only a few certifications available for editors, such as those offered by the Editors’ Association of Canada and the Board of Editors in the Life Sciences, and many academic degree programs and courses are out there, lots of them offered by profession-related associations. But there are no national licensing boards for editors, and editing itself is still largely learned on the job, often as sort of an apprenticeship. And editing is a solitary occupation; we editors don’t usually sit around in groups and edit, unless we’re members of one of the rapidly disappearing newsroom copy desks. All of that can make it hard for individual editors to judge their own skill levels. Chris Galan asked about this issue recently on the private e-mail list of the Editorial Freelancers Association (EFA). She received some very helpful responses, which I’m sharing here with the permission of everyone quoted.”
