Description of the ACT
The ACT (No Writing) consists of four multiple-choice tests: English, Mathematics, Reading, and Science. The ACT Plus Writing includes the four multiple-choice tests and a Writing Test.
Test | Content | ||
English | 75 questions | 45 minutes | Measures standard written English and rhetorical skills. |
Mathematics | 60 questions | 60 minutes | Measures mathematical skills students have typically acquired in courses taken up to the beginning of grade 12. |
Reading | 40 questions | 35 minutes | Measures reading comprehension. |
Science | 40 questions | 35 minutes | Measures the interpretation, analysis, evaluation, reasoning, and problem-solving skills required in the natural sciences. |
Optional Writing Test | 1 prompt | 30 minutes | Measures writing skills emphasized in high school English classes and in entry-level college composition courses. |
