To score well on ACT Writing, optimize for each of the four rubric domains separately: Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions—each is scored 1–6 by two graders. Weakness in one domain caps your overall score even if the rest is strong. Extends ACT Writing score explained.
Ideas and Analysis
Score 6: clear, nuanced perspective; all three given viewpoints engaged analytically—not just summarized.
Score 3: vague thesis; perspectives mentioned but not analyzed; position unclear or purely descriptive.
Fix: write one sentence per perspective explaining what it gets right and where it falls short.
Development and Support
Score 6: specific, well-explained examples that clearly support each claim; reasoning is explicit.
Score 3:generic statements ("technology helps society"); examples missing or not connected to the argument.
Fix:for every claim, add "for example…" with a concrete detail and one sentence explaining why it matters.
Organization
Score 6: logical intro → body → conclusion; one main idea per paragraph; clear transitions.
Score 3: ideas jump around; missing conclusion; reader loses the thread.
Fix: use the five-part template in ACT essay format and template; outline before drafting.
Language Use and Conventions
Score 6: clear, varied sentences; few grammar or spelling errors; word choice is precise without being pretentious.
Score 3: frequent errors that obscure meaning; repetitive or awkward phrasing.
Fix: reserve two minutes at the end to reread for subject-verb agreement, comma splices, and misspellings.
