Organization and Coherence
What this domain tests
Organization and Coherence tests whether a passage holds together as a unit. It examines paragraph focus, logical order, transitions, and the reader’s ability to follow the writer’s purpose without guesswork.
Core rules
- Unity: One paragraph should develop one controlling idea. Every sentence should support, explain, or illustrate that idea; off-topic detail belongs elsewhere.
- Topic sentences: A clear topic sentence announces the paragraph’s focus. It need not be the first sentence in every paragraph, but the opening should orient the reader.
- Logical order: Arrange ideas by chronology, cause and effect, comparison, or order of importance. Keep the same principle throughout a paragraph.
- Cohesion: Link sentences with transitions that show the actual relationship: however for contrast, therefore for result, for example for illustration, meanwhile for time. Do not use a transition as decoration.
- Given-to-new flow: Put familiar information early and new information late. Repeat key nouns or use pronouns only when the antecedent is unambiguous.
- Purpose and audience: Match tone and detail to the reader. A formal briefing needs explicit recommendations and evidence, not casual asides.
Worked example
The pilot reduced processing time by 18 percent. Staff reported fewer duplicate entries. The pilot ran for six weeks. The agency expanded it to two regions. The chronology is interrupted: the six-week duration belongs before the results, or it can be attached to the pilot in a single sentence. A coherent revision is: The six-week pilot reduced processing time by 18 percent, and staff reported fewer duplicate entries. As a result, the agency expanded it to two regions. The transition As a result makes the causal link explicit, and six-week removes a choppy standalone sentence.
Traps that cost marks
- Choosing a transition by sound rather than logic: The deadline was extended, therefore the team finished early reverses cause and result.
- Starting a new paragraph with an unexplained pronoun: This shows that... with no clear referent.
- Putting a broad generalization after specific evidence, which makes the paragraph feel backward.
- Treating first, second, finally as organization when the items are not parallel or not in that order.
- Adding a relevant fact that does not support the paragraph’s controlling idea; relevance to the topic is not the same as relevance to the point.
