Certain skills can be taught. With editing, I believe that you either have the "eye" or you don't.
Like any other skill, though, editing can — and must — be honed over time. I keep this skill sharp through a mix of on-the-job training, formal training and an unhealthy amount of time on Grammar Girl.
Whether it's piecing together a report with many contributors, proofreading an email for errors or providing substantive editing on a press release, I've proven that I have both the eye and the responsibility to make the written word as powerful as it deserves to be.
I'm a quick learner in any editing style, but I'm most familiar with AP, GPO and APA styles.
Most of my training has been on the job — the best type of training. But I also lucked out by getting to take a comprehensive proofreading course at EEI Communications.
Editing samples never look as glamorous as writing samples, but I have them nonetheless. Contact me if you're interested in seeing a few.
