The ACT contains four multiple-choice tests—English, mathematics, reading, and science—and an optional writing test.  These tests are designed to measure skills that are most important for success in postsecondary education and that are acquired in secondary education.  The score range for each of the four multiple-choice tests is 1–36.  The Composite score is the average of the four test scores rounded to the nearest whole number. 

• The ACT mathematics test assesses the skills students typically acquire in courses taken through grade 11. The material covered on the test emphasizes the major content areas that are prerequisites to successful performance in entry-level courses in college mathematics. Knowledge of basic formulas and computational skills are assumed as background for the problems, but recall of complex formulas and extensive computation are not required.

• The ACT reading test measures the ability to read closely, reason logically about texts using evidence, and integrate information from multiple sources. The test questions focus on the mutually supportive skills that readers must bring to bear in studying written materials across a range of subject areas. Specifically, questions will ask you to determine main ideas; locate and interpret significant details; understand sequences of events; make comparisons; comprehend cause-effect relationships; determine the meaning of context-dependent words, phrases, and statements; draw generalizations; analyze the author’s or narrator’s voice and method; analyze claims and evidence in arguments; and integrate information from multiple texts.

• The ACT science test measures the interpretation, analysis, evaluation, reasoning, and problem-solving skills required in the natural sciences. The test presents several authentic scientific scenarios, each followed by a number of multiple-choice test questions. The content of the test includes biology, chemistry, Earth/space sciences (e.g., geology, astronomy, and meteorology), and physics. The questions require you to recognize and understand the basic features of, and concepts related to, the provided information; to examine critically the relationship between the information provided and the conclusions drawn or hypotheses developed; and to generalize from given information to gain new information, draw conclusions, or make predictions.
