The ACT was launched in 1959 by University of Iowa professor Everett Franklin Lindquist.[1] The test's name was originally an acronym for "American College Testing", but today, the full name of the test and its administering organization is simply "ACT."[2] Before the development of the ACT, the SAT was the only national standardized college entrance examination in the United States.[3] In contrast to the SAT, which was designed to measure scholastic aptitude, the ACT was designed to be a test of academic achievement and preparation. As such, ACT scores can be used for course placement purposes as well as for university admissions.[3]

The test was originally divided into sections on English, mathematics, social studies, and natural sciences, each assessed on a grade scale from 1 to 36. In 1989, a major overhaul replaced the social studies section with a reading section and changed the natural sciences section to a science reasoning section.[3] Further, an optional writing section was added to the test in 2005.[4]

In 2010, the number of students taking the ACT surpassed the number of students taking the SAT for the first time.[5]

Function of the Test

ACT Study Guide

The ACT is primarily taken by college-bound students for university admissions and course placement purposes. Every four-year college and university in the United States accepts ACT results for admissions purposes.[6] Its scores are also used for diagnostic and monitoring purposes for high school students. For example, in twelve states, high school students are required to take the examination for statewide assessment purposes.[6] In 2012, 52% of students graduating from high school in the United States took the ACT; however, only 25% of those test-takers met each ACT sub-section's College Readiness Benchmark score, a score which indicates a 50% likelyhood of obtaining a B or higher in a corresponding first-year college course.[6] In fact, in 2012, the national average scores of the math (21.1), reading (21.3), and science reasoning (20.9) sub-sections all fell below the Benchmark score of 22.[7][8]

Historically, universities throughout the midwestern and southern United States were more likely to require prospective students to submit ACT scores, whereas the SAT was the dominant entrance examination on the East and West Coasts. In the 21st century, however, both examinations have become less regionally-defined as universities compete for students from all fifty states.[9] As such, ACT functions as a nationwide university admissions examination on par with the older SAT.

Test Administration

ACT Flashcards

The ACT is administered in all fifty states. Most testing sites are at schools and universities.[10] There are six test dates per year: one each in September, October, December, February, April, and June.[11] The ACT may also be taken in dozens of other countries worldwide, but test dates and availability may vary from location to location.[12] The registration fee for the basic ACT examination is $35, but students who also wish to take the optional writing section must pay a total of $50.50. The testing time of the basic ACT examination is two hours and 55 minutes, and the optional writing section adds another forty minutes of testing time.[6]

Students with disabilities or special needs may request one of three special testing protocols. National Standard Time with Accomodations is a testing protocol which allows students to receive appropriate accomodations in a normal examination setting such as a large-type test booklet, a sign language interpreter, permission for diabetics to eat snacks in the test room, or some other disability-specific accomodations. National Extended Time is a testing protocol which gives students 50% more time to complete the examination. Finally, Special Testing is a protocol for more specific needs, such as students who require testing to be spread out over multiple days or who use alternate test formats such as Braille or cassettes. Requesting a special testing protocol does not alter the cost of the examination.[13]

Students may only take the ACT a total of twelve times, not including mandatory state testing. [14]

Test Environment

The test begins at 8:00 a.m. Each student must bring their admission ticket as well as a photo ID in order to be admitted into the testing room. The exam is a written exam with a test booklet that allows test takers to answer questions from every section. Any four-function, scientific, or graphing calculators are permitted, but only for the math sections. Calculators with built-in algebra systems are prohibited. The ACT Test usually ends around 12:15 to 1:00 in the afternoon, depending on whether the test taker opts to complete the writing portion as well. Dress comfortably. Snacks and drinks are allowed during the breaks, so come prepared.[16]

Test Structure

The ACT Test is divided into four sections. Each of these four sections test students over what they've learned up to the beginning of 12th grade in English, Science, Mathematics, and Reading. Depending on whether it is the ACT (No Writing) or ACT Plus Writing, there will also be a writing test with one prompt. There is a total of 215 questions that, including the breaks, will take close to four hours to complete (four and a half with the optional essay.)[17]

Test Content

The following are the topics covered by each of the four ACT tests along with what percentage portion those topics are of that particular test.

  • The English test includes questions on:
-Usage/Mechanics: Punctuation (13%), Grammar and Usage (16%), and Sentence Structure (24%).
-Rhetorical Skills: Strategy (16%), Organization (15%), and Style (16%).
Sample English Questions:
Numbers 1 and 2 pertain to the following passage:
The Sistine chapel holds a magnificent collection of Renaissance frescoes. The restoration of these frescoes (1) is an important 20th century event in the art world.
Completed in about 1481, (2) the chapels’ walls were decorated by important Renaissance painters including Perugino and Botticelli. The paintings done in the 1500s by Michelangelo enhanced the artistic magnificence of the chapel.
  1. A. no change
    B. was important 20th century events
    C. was an important 20th century event
    D. were an important 20th century event
  2. F. no change
    G. the chapel’s walls
    H. the chapel’s wall
    J. the chapels walls
  • The Reading test includes passages on: Social Studies (25%), Natural Sciences (25%), Literary Narrative or Prose Fiction (25%), and Humanities (25%). The focus of this test is reading comprehension rather than factual knowledge in any of the four domains.
Sample Reading Questions:
Numbers 1 and 2 pertain to the following passage:
Comets are bodies that orbit the sun. They are distinguishable from asteroids by the presence of coma or tails. In the outer solar system, comets remain frozen and are so small that they are difficult to detect from Earth. As a comet approaches the inner solar system, solar radiation causes the materials within the comet to vaporize and trail off the nuclei. The released dust and gas forms a fuzzy atmosphere called the coma, and the force exerted on the coma causes a tail to form, pointing away from the sun.
Comet nuclei are made of ice, dust, rock and frozen gases and vary widely in size: from 100 meters or so to tens of kilometers across. The comas may be even larger than the Sun. Because of their low mass, they do not become spherical and have irregular shapes.
Many comets and asteroids have collided into Earth. Some scientists believe that comets hitting Earth about 4 billion years ago brought a significant proportion of the water in Earth’s oceans. There are still many near-Earth comets.
  1. What does the passage not list as a component of comet nuclei?
    A. solar radiation
    B. dust
    C. frozen gases
    D. rock
  2. According to the passage, what do some scientists believe brought a significant proportion of the water in the Earth’s oceans?
    F. Comets’ released gas and dust
    G. Comets exiting in the solar system
    H. Comet collisions with the Sun
    J. Comet collisions with Earth
  • The Mathematics test includes questions on:
-Pre-Algebra/Elementary Algebra: Pre-Algebra (23%) and Elementary Algebra (17%).
-Intermediate Algebra/Coordinate Geometry: Intermediate Algebra (15%) and Coordinate Geometry (15%).
-Plane Geometry/Trigonometry: Plane Geometry (23%) and Trigonometry (7%).
Sample Mathematics Questions:
  1. If 3x – 2 = 5x -12, x = ________
    A. 10
    B. 5
    C. 3
    D. 2

    F. 8
    G. 16
    H. 32
    I. 40
    J. 44
  • The Science test includes questions on: Data Representation (38%), Research Summaries (45%), and Conflicting Viewpoints (17%). The focus of this test is the ability to scientifically deal with information provided rather than advanced factual knowledge.
Sample Science Questions:
Numbers 1 and 2 pertain to the following passage:
A group of scientists have built a knee-mounted device that can harvest energy from a person's walking power. The device, which weighs about 1.6 kilograms, can generate an average of five watts of electricity with minimal extra effort on the part of the walker. It gets its energy not from the power used to move the leg forward, but from the energy put into slowing down the knee at the end of a person's step. The concept is similar to that used by hybrid-electric cars which recycle power from braking.
  1. According to the passage, which of the following is true?
    A. The device weighs about 1.6 kilograms and requires a great deal of extra metabolic power to produce energy.
    B. The device weighs about 1.6 pounds and requires a great deal of extra metabolic power to produce energy.
    C. The device weighs about 1.6 kilograms and requires little extra metabolic power to produce energy.
    D. The device weighs about 1.6 pounds and requires little extra metabolic power to produce energy.
  2. According to the passage, from where does the device get its energy?
    F. the power to move the leg forward
    G. energy put into slowing down the knee
    H. a backpack battery
    J. a pacemaker

Each of the four primary sections of the ACT—English, Mathematics, Reading, and Science Reasoning—are scored on a scale from 1 to 36. These scaled scores are calculated based on students' raw scores, meaning that there is no penalty for guessing or for answering questions incorrectly. Students also receive an overall composite score, which is the average of their four scaled test scores rounded to the nearest whole number.[19]

The ACT offers an optional writing test. This test does not affect students' scores on the other four sections or change the composite score. Rather, students who choose to take the writing test receive two additional scores: a Writing score and a Combined English/Writing score. The Writing section is scored by two trained readers on a holistic scale from 1 to 6. These two ratings are combined to yield a final score from 2 to 12. The Combined English/Writing score is reported on a scale from 1 to 36. It is a score which combines students' performance on the English and Writing sections, but gives more weight to the score of the English section.[20][21]

ACT, Inc. publishes national ranks for every composite score and sub-section test score to their website. For example, among recent test-takers, 26% of students achieved a composite score of at least 24, whereas 78% of students achieved a composite score of at least 16. Due to rounding, there is no precise "average" score, but 51% of students scored 20 or higher.[18] This score falls well within normal admissions boundaries for most universities. However, the more selective a school is, the higher its accepted students' composite scores tend to be.[22] For example, 75% of students entering Ivy League universities in 2009 scored at least 29 on the ACT, and 25% of them scored at least 34.[23]

Recent and Future Developments

In May 2013, ACT Inc. announced that a computer-based version of the ACT test was under development and is scheduled to be deployed in the spring of 2015. Its contents will be identical to the paper examination. The computerized version of the examination will be available on tablets in addition to traditional computers. Testing centers which lack the proper facilities to offer the computerized version of the ACT will be able to continue offering the paper-based version.[24]
