That’s not how professional writers or people who work at publishing companies use the term. For us, editing involves reading a manuscript written by someone else and providing feedback. The person who does this job is called an editor.Many schools include “buddy editing” or “peer editing” as a step in the writing process. This is the proper way to use the word “editing” as long as the student reader is providing substantial feedback (not just checking conventions).
In a school setting, the teacher is the primary editor. The teacher-editor guides the writer by asking questions and making specific, gentle suggestions that will help the writer improve the manuscript . Then the writer uses those comments as he/she revises.
Professional writers rely on proofreaders employed by their publishing company to check conventions. This is a tiny little step at the very end of the process, just before the manuscript goes to the printer.
As educators work to emulate the professional writing process with their students, I hope that they will modify the way they use the term “editing” and introduce the term “proofreading” to describe the final step of the writing process.
