ACT Writing

Short story: The ACT Writing section is no longer graded on a curve, so there are no scales.

Long Story: In 2015, the ACT (stupidly) decided to score the writing section from 1 to 36 using a curve. In September 2016, the ACT finally realized it was a mistake and changed the scoring back to 2-12. If you’d like to convert a score from the 1-36 range to the 2-12 range, use the official conversion table.

How Your Essay is Graded: Once your essay is sent in, two readers each give it a score from 1-6 in four categories: Ideas and Analysis, Development and Support, Organization, Language Use and Conventions. The scores for each category are summed up to get the category’s Domain Score.

1st Reader2nd ReaderDomain Score
1-61-62-12
Ideas and Analysis _____________ + _____________ = _____________
Development and Support _____________ + _____________ = _____________
Organization _____________ + _____________ = _____________
Language Use and Conventions _____________ + _____________ = _____________

The four Domain Scores are then added up to get a value between 8 and 48. Finally, that value is divided by 4 to get your final writing score (2 to 12), the one colleges look at.
