Do typos jump off the page at you? Do you gasp when a lone em dash suddenly appears among a sea of en dashes? Do you see gaps in a page, or notice lines sitting all by themselves? Do you stare at a photo, wondering whether it has been reversed? By the time you complete this introductory course on proofreading for businesses and ad agencies, you’ll be answering “yes” to all of these questions.

Corporate proofreading is a significant and lucrative field of editing, but there are specific nuances to working with businesses and ad agencies; the five modules of this course focus on proofreading and fact-checking corporate materials. This course does not cover proofreading or editing of novels, magazines or non-fiction materials.

  • Week 1 provides an overview of proofreading, including definitions, and the differences between proofreading and copyediting. We’ll also cover what skills a corporate proofreader needs, how to get (or sharpen) those skills, and where to find equipment and tools.
  • Week 2, which gets into the nitty-gritty of proofreading, covers different types of strategies and processes, and offers several handy checklists. I’ll also introduce you to fact-checking—an essential part of corporate proofreading.
  • Week 3 covers more information about fact-checking, including an assignment. We’ll also touch lightly on some mechanics of writing, and you’ll see lists of common spelling errors, grammar basics, commonly confused words, country-based spelling differences, punctuation basics, and buzzwords, jargon and wordiness to avoid.
  • Week 4 walks you through style resources available, and through using a basic writing style guide/glossary for each client—and for your client’s clients. If you haven’t used a writing style guide/glossary in the past, you’ll wonder how you ever managed without one!
  • Week 5 is all about markup. Once you’ve found all those errors, you need to let your client know what they are and how to fix them—usually via tracked changes in a Word doc or by marking up a PDF. We’ll also take a very, very quick glance at proofreader’s marks, and give you some resources to learn how to use them.

Each week, there will be a short, self-marked assignment. An answer key will be provided, and you’ll have the opportunity to review your assignment and the answers with the instructor. In the forum, you can discuss the assignments and answer keys further with the instructor and with your fellow students. Expect to spend 1–2 hours per week on assignments, and 1–2 hours per week in forum discussions.

No previous proofreading experience is needed, but it helps if you have a sharp eye, the ability to focus in on details, and a fairly long attention span. Most importantly, you need the patience to double-check everything, and an interest in working with businesses and ad agencies. If that appeals to you, this course will give you everything you need to launch your corporate proofreading career or add to your existing editing business.
