The Auto and Shop Information section of the ASVAB test measures your knowledge of automobile technology and basic repairs. The shop questions are about basic wood and metals. For example, you will encounter questions such as “Shock absorbers on a car connect the axle to the: wheel, chassis, drive shaft, or exhaust pipe?” You may be asked what sanding blocks are used for, followed by the following choices: preventing high spots and ridges on sanded surfaces, preventing dirt from collecting on the sandpaper, stretching the length of sandpaper, or prolonging the use of the sandpaper. The CAT-ASVAB test has two parts: the first part covering automotive material asks 11 questions in 7 minutes; the 11 shop information questions are allotted 6 minutes. The paper-and-pencil version asks 25 questions in 11 minutes.
Military tactics concerns itself with the methods for engaging and defeating the enemy in direct combat. Military tactics are usually used by units over hours or days, and are focused on the specific, close proximity tasks and objectives of squadrons, companies, battalions, regiments, brigades, and divisions, and their naval and air force equivalents.
A graphic view of the increasing trend in AFQT performance of accessions from FY 1981 through FY 1992 is provided in Figure 2.8. The more significant gains were in Categories I to IIIA, where the percentages increased from 47 percent in FY 1981 to 75 percent in FY 1992. Conversely, there has been a steady decline in the percentage of Category IIIB accessions. Most dramatic has been the decrease in accessions who score in Category IV—from 33 percent in FY 1979 to one percent or less since FY 1991. There has been a gradual decline in the percentage of accessions in Categories I to IIIA in the last seven years, from 75 to 65 percent.
The IRT model underlying ASVAB scoring is the three-parameter logistic (3PL) model. The 3PL model represents the probability that an examinee at a given level of ability will respond correctly to an individual item with given characteristics. Specifically, the item characteristics represented in the 3PL model are difficulty, discrimination (i.e., how well the item discriminates among examinees of differing levels of ability), and guessing (i.e., the likelihood that a very low ability examinee would respond correctly simply by guessing).
In order to perform well on the ASVAB, you should take a practice test to get an idea of what you’ll encounter on the actual test. Also, completing a practice test will help you to feel more at ease on test day. Reading the test instructions and focusing your full attention on each question are both important steps to take. As you work through the test, avoid spending too much time on a single question. The test has a time limit and you don’t want to fall into the trap of running out of time before you arrive at the end of the test. Taking the time to provide thoughtful answers to test questions allows you to offer a clear picture of your skills and capabilities. Earning a high score on the ASVAB may give you more options when it comes to choosing a specialty.
Each year, many high school and postsecondary students take the free Armed Services Vocational Aptitude battery (ASVAB). The ASVAB is the most widely used multiple-aptitude test battery in the world. It consists of eight tests that measure your skills and abilities in the following areas: General Science; Arithmetic Reasoning; World Knowledge; Paragraph Comprehension; Mathematics Knowledge; Electronics Information; Auto and Shop Information; Mechanical Comprehension.
The increasing importance of cinema in the early 20th century provided a new platform for depictions of military subjects. During the First World War, although heavily censored, newsreels enabled those at home to see for themselves a heavily sanitised version of life at the front line. About the same time, both pro-war and anti-war films came to the silver screen. One of the first films on military aviation, Hell's Angels, broke all box office records on its release in 1929. Soon, war films of all types were showing throughout the world, notably those of Charlie Chaplin who actively promoted war bonds and voluntary enlistment.
Mathematics Knowledge tests the ability to solve problems by applying knowledge of mathematical concepts and applications. The problems focus on concepts and algorithms, and involve number theory, numeration, algebraic operations and equations, geometry, measurement and probability. Mathematics Knowledge is one factor that characterizes mathematics comprehension; it also assesses logical thinking.
