Developmental editing, line editing, copy editing, fact-checking, and proofreading compared

What to take away

• Editing stages solve different problems and should occur in a sensible order.
• Developmental work can move or remove whole sections.
• Copy editing refines accepted language and consistency without proving every fact.
• Fact-checking tests claims against evidence.
• Proofreading checks a stable production version for residual and introduced errors.

One editor may perform several roles, but the passes should remain conceptually separate. If a team proofreads while the structure is still moving, it will repeat work and miss new errors. If a copy editor is treated as the sole fact-checker without sources or time, factual risk becomes invisible.

Stage comparison

Stage	Main unit	Central question	Typical output
Developmental editing	Whole article	Does focus, evidence, order, and proportion work?	Structural memo and revised map
Line editing	Paragraph and sentence	Is the prose clear, purposeful, and true to the voice?	Tracked language edits
Copy editing	Sentence and package	Is the copy correct, consistent, clear, and styled?	Edited manuscript and queries
Fact-checking	Claim and implication	What evidence supports this statement?	Claim sheet and corrections
Legal review	Specific legal risk	Does publication create avoidable legal exposure?	Advice and required decisions
Sensitivity reading	Representation and impact	What may be inaccurate, harmful, or missing in portrayal?	Contextual feedback
Production editing	Layout and platform	Does the package work in its final form?	Fitted text and package updates
Proofreading	Final proof	What residual or production error remains?	Corrected proof

Revision is not proofreading

Hamilton College's guide to revision strategies distinguishes revision of argument, ideas, focus, nuance, and style from editing surface errors. That difference explains why a structural review belongs before close correction of sentences and production details.

Developmental editing comes first because it changes the article's architecture. Line and copy passes follow when the sections and evidence are stable enough to justify close attention. Fact-checking can begin during reporting, but its final pass needs near-final language so every implication can be examined.

The handoff between stages should identify open questions, accepted exceptions, and any material that still requires specialist review. Without that record, the next editor may mistake unresolved content for approved copy.

Copy editing versus fact-checking

A copy editor should flag doubtful names, dates, numbers, logic, and attribution. A fact-checker independently traces claims through the source packet and outside confirmation where required. The same person can do both only if the schedule, materials, and workflow make the switch explicit.

Poynter's collection of copy-editing protocols distinguishes routine corrections from substantive changes that require consultation and stresses reading the whole story before questioning or editing isolated passages. The exact authority line varies by publication, so teams should document it rather than rely on habit.

Proofreading and production

Proofreading begins after copy is placed or otherwise rendered in its final channel. Check widows and breaks, headings, folios, captions, credits, jumps, links, tables, footnotes, pull quotes, symbols, special characters, and changes introduced during fitting. A late factual rewrite must return to fact-checking, not receive only a typographical glance.

Design a realistic sequence

Use stage gates rather than one vague status called "editing." Record who owns each pass, what input is required, what can still change, who approves high-risk changes, and what sends the article backward. A clean proof is the result of resolved work, not proof that all prior work occurred.

Common questions

Does every article need all eight stages?

No. Match roles to length, subject, risk, format, and resources while keeping necessary checks explicit.

Is line editing the same as copy editing?

They overlap, but line editing concentrates more on expression and rhythm while copy editing emphasizes correctness and consistency.

When should legal review happen?

Raise likely issues early and review near-final wording before release.

Can proofreading change meaning?

It should not silently do so. Return substantive changes to the appropriate editor and checker.
