The ACT Test
About the ACT Test
The gold standard in standardized assessments
The ACT® test motivates students to perform to their best ability. Test scores reflect what students have learned throughout high school and provide colleges and universities with excellent information for recruiting, advising, placement, and retention.
Many times, students who are not considering higher education rethink their plans when they see their ACT test results. This is especially true for underrepresented students. To support college and career planning, the ACT also offers a career exploration component to help students identify career options.

The ACT College and Career Readiness Standards are the backbone of ACT assessments. The standards are empirically derived descriptions of the essential skills and knowledge students need to become ready for college and career, giving clear meaning to test scores and serving as a link between what students have learned and what they are ready to learn next.
When students take the ACT test, high school educators and counselors receive valuable information for guidance and curriculum development. K-12 professionals use ACT reports to
- Guide students toward college and career readiness
- Assist students with college and career planning
- Evaluate the effectiveness of instruction
- Plan changes and improvements in curriculum
The ACT Test User Handbook for Educators offers the most comprehensive information for K-12 professionals about the ACT Test. In addition to detailed information about updates to the test, accommodations, and reports, the handbook offers helpful tips about
- Preparing for and Taking the ACT

What the ACT Measures
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 English test measures understanding of the conventions of standard English, production of writing, and knowledge of language.
The ACT mathematics test assesses the skills students typically acquire in courses taken through grade 11. The test questions require the use of reasoning skills to solve practical problems in mathematics. Knowledge of basic formulas and computational skills are assumed, but recall of complex formulas and extensive computation is not required.
The ACT reading test measures reading comprehension. The questions require the use of referring and reasoning skills 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; and analyze voice and method.
The ACT science test measures the interpretation, analysis, evaluation, reasoning, and problem-solving skills required in the natural sciences. Scientific information is conveyed in one of three formats: data representation, research summaries, or conflicting viewpoints. Questions require recognition and understanding of the basic features of, and concepts related to, the provided information; the critical examination of the relationship between the information provided and the conclusions drawn or hypotheses developed; and the generalization of given information to gain new information, draw conclusions, or make predictions.
The optional ACT writing test is an essay test that measures writing skills taught in high school English classes and entry level college composition courses. The test describes an issue and provides three different perspectives on the issue. Each student must (1) analyze and evaluate the given perspectives, (2) state and develop a perspective on the issue, and (3) explain the relationship between that perspective and those given. Colleges may view student essays using the free ACT Essay View tool.
Complete information about the ACT test is available in the technical manual.

Help students remove the guesswork in finding a test center. Your school can request to be a test center for students taking the ACT on a national test date. As a test center, your school provides:
- A staff member to serve as the Test Supervisor
- Other school staff willing to serve as room supervisors and proctors
- Space for testing on ACT National Testing dates
- Quiet areas—free from distractions and other events
- Classrooms, preferably, with full-sized desks
- Plenty of space between examinees, for security purposes
- A secure location to store test materials
There are currently more than 7,500 ACT test centers in operation around the world, and more than 80 percent of them are operated in local high schools.
Complete the ACT Test Center Request form if you would like your institution become an ACT Test Center.
More than three thousand colleges, universities, and scholarship agencies use ACT test scores to make decisions about admission, scholarship awards, and course placement. Because these institutions, as well as the examinees, rely on the integrity of ACT test scores, ACT takes seriously the importance of reporting valid test scores.
In addition to conducting our own internal score reviews, ACT regularly receives inquiries from college admissions officers, high school counselors, and others who have concerns about an individual examinee's score.
You can report concerns using ACT's Score Inquiry form. ACT will review the inquiry and investigate the validity of the scores. If you prefer, you may submit an inquiry anonymously online or by calling 855.382.2645 to use our dedicated Test Security Hotline.
If ACT initiates a score review, ACT will notify the examinee directly. For privacy reasons, ACT generally does not discuss the details of a score review with anyone other than the examinee unless the examinee expressly authorizes us to do so by executing an Authorization to Release Personal Information form.
Only official score recipients will receive notice of ACT’s decision regarding the validity of the scores. For your institution to be an official score recipient, the examinee must request that ACT send the score report to your institution. An examinee can send official scores by logging into his/her ACT web account and choosing "Send Your Scores."
For complete details of ACT's score review process, please see Procedures for Investigating Testing Irregularities and Questioned Test Scores (PDF).
