Clean grammar gets you a test edit. It doesn't get you the job. The skills below are sorted by when they start to matter, so you can stop polishing the ones hiring managers take for granted and build the ones they actually argue about.
| Certificate | Best for | Effort | Worth it? |
|---|---|---|---|
| ACES Certificate in Editing (with Poynter) | Writers and early-career editors who want a structured grounding in copy editing and a line for the résumé | a few weekends of self-paced online work | Worth it if you're switching in from another field. Editors already holding clips can skip it, since the test edit counts for more. |
| University of Chicago Graham School Certificate in Editing | People aiming at book, academic or Chicago-style publishing | several months of evening courses | A serious, recognised program that teaches real craft. It costs real money, so take it if book publishing is your target, not just to decorate a résumé. |
| UC Berkeley Extension Professional Sequence in Editing | Career changers who want graded feedback on their edits from working editors | a few months of part-time courses | Good for building confidence and a portfolio fast. Hiring managers value what you can show from it more than the credential itself. |

Edited articles for the website and helped with content.
Edited 12 features a month for a 40,000-subscriber newsletter, restructured weak drafts before layout, and cut average turnaround from 5 days to 3.
Learn the one your target field uses. News sites, marketing teams and PR shops mostly run on AP. Book publishers and a lot of academic presses use Chicago. Once you know one well, picking up the other takes a couple of weeks.
Practise on real, unedited copy under a timer. Keep the style guide open, fix the structure before the commas, and leave short queries for anything you can't verify. Graders look for judgment on what to change and what to leave alone.
Not deeply, but you should be comfortable fixing a broken link, a stray heading tag or a messy paste from Word inside the CMS. That little bit saves a developer a ticket and makes you easier to hand work to.
Giving feedback that a writer can act on. You can teach yourself style rules from a book, but coaching gets better only when someone senior reads your notes and tells you where they landed badly.
