The CAT-ASVAB is a computer-based exam that is only provided at Military Entrance Processing Stations (MEPS) for enlistment purposes. The test is customized based on the taker’s answers, so if one question is answered correctly, the next one will be more difficult. This exam is timed, although users have the option of pacing themselves throughout the exam. However, it is not possible to go back through the test and check answers or change responses after they have been submitted. The CAT-ASVAB is broken down into 10 subparts, including basics such as arithmetic and verbal skills as well as auto information, electronics, shop, and mechanical knowledge.
There is another ASVAB score that's equally important, if not more so, because it is the score that determines if a person is eligible for military service. It's the Armed Forces Qualification Test score, or AFQT score. This score is calculated from only four of the nine Standard Scores on the ASVAB - Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). First, the WK and PC scores are added together, then the sum is doubled. This is known as the Verbal Expression (VE) score. The VE, MK, and AR scores are then added together, and the sum is the AFQT. This score is a straight percentile measure, expressed as a number from 1-99. The number is the percentage of people who scored lower than the test taker. For example, if a person receives an AFQT score of 63, that means that he did better on the test than 63% of the people who have taken it.
These forces demobilized in 1784 after the Treaty of Paris ended the War for Independence. The Congress of the Confederation created the current United States Army on 3 June 1784. The United States Congress created the current United States Navy on 27 March 1794 and the current United States Marine Corps on 11 July 1798. All three services trace their origins to their respective Continental predecessors. The 1787 adoption of the Constitution gave the Congress the power to "raise and support armies", to "provide and maintain a navy" and to "make rules for the government and regulation of the land and naval forces", as well as the power to declare war. The President is the U.S. Armed Forces' commander-in-chief.
You can take the test as a junior or senior in high school and use the score to enlist, provided that you are at least 17 years old and took the test no earlier than 2 years before you begin enlistment processing. If you are at least 17, you can take the test at a Military Processing Station (MEP) or a satellite Military Entrance Test (MET) location.
Examinees also receive a score on what is called the Armed Forces Qualification Test (AFQT). AFQT scores are computed using the Standard Scores from four ASVAB subtests: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). AFQT scores are reported as percentiles between 1-99. An AFQT percentile score indicates the percentage of examinees in a reference group that scored at or below that particular score. For current AFQT scores, the reference group is a sample of 18 to 23 year old youth who took the ASVAB as part of a national norming study conducted in 1997. Thus, an AFQT score of 90 indicates that the examinee scored as well as or better than 90% of the nationally-representative sample of 18 to 23 year old youth. An AFQT score of 50 indicates that the examinee scored as well as or better than 50% of the nationally-representative sample.
The ASVAB tests recruits in ten different areas. It is presented as ten short tests administered over a three-hour period. Traditionally, the ASVAB is a “proctored” test, meaning that it has required supervision to administer in order to maintain the integrity of the test. However, changes to military recruiting and technology in general have helped the ASVAB evolve as a 21st century tool.
Individuals can also complete a computer version of the test. This is an adaptive test, meaning the difficulty level of each question is determined based on whether the previous question was answered correctly or incorrectly. Aside from the fact that this version of the AFQT is a computer adaptive test, the number of questions that must be answered varies from the written version of the assessment. Individuals only need to answer a total of 59 questions. 89 minutes is allotted for the four sections of the Armed Forces Qualification Test, and test-takers typically have more than enough time to complete each section.
In exchange for a service commitment, the Reserve Officers' Training Corps (ROTC) program provides you with money for college while you're in school. You must take one military science course along with your other college courses and, upon graduation, enter the service as a commissioned officer. (There is no military commitment for the first year in ROTC, allowing you to pursue ROTC on a trial basis to see if ROTC is for you.) Full ROTC scholarships pay for almost all tuition, fees and books charges for four years of college. ROTC scholarships also come in one, two and three-year lengths. For more information, call 1-800-USA-ROTC (Army), 1-800-USA-NAVY (Navy), 1-866-423-7682 (Air Force) and 1-800-MARINES (Marines).
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 Armed Forces Qualification Test (AFQT) covers four sections from the Armed Services Vocational Aptitude Battery (ASVAB): Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge. These four sections and your scores on them make up the Military Entrance Score, also known as the AFQT. Your AFQT score is used to determine your eligibility for entrance into the Armed Services.
The President, Secretary of Defense and other senior executive officials are advised by a seven-member Joint Chiefs of Staff, which is headed by the Chairman of the Joint Chiefs of Staff, the highest-ranking officer in the United States military and the Vice Chairman of the Joint Chiefs of Staff.[20] The rest of the body is composed of the heads of each of the DoD's service branches (the Chief of Staff of the Army, the Chief of Naval Operations, the Commandant of the Marine Corps and the Chief of Staff of the Air Force) as well as the Chief of the National Guard Bureau. Although commanding one of the five military branches, the Commandant of the Coast Guard is not a member of the Joint Chiefs of Staff. Despite being composed of the highest-ranking officers in each of the respective branches, the Joint Chiefs of Staff does not possess operational command authority. Rather, the Goldwater-Nichols Act charges them only with advisory power.[21]

You should note that the exam is given only in English. This is because all of the documents you will need to reference during your military career are in English. Even if English is not your native language, you should be able to make the cut as long as you study enough. You may need to take another test, the ECL (English Comprehension Level), to make sure that you can read and follow instructions given English if it is not your native language.

The scores from the other tests are used to determine what type of specialty you might be best suited for.  These "composite" scores (also known as line scores, MOS scores, or aptitude area scores) are calculated by adding together combinations of the different sub test standard scores. These composite scores are then used to determine which different military jobs (aka Military Occupational Specialties or MOS) may be the best fit for you.  Each branch of the military will have their own approach to these composite scores.

On the CAT-ASVAB, you answer one question at a time and can’t go back and change your answers once you’ve submitted them. If you answer a question correctly, you get a more difficult question, but if you are incorrect, you are given an easier question to answer. This is called “adaptive” testing. Once you finish a section you can go on to the next section at your own pace.

The adaptive test is exactly what it sounds like, a test that adapts to the test taker. Questions in each section range in difficulty, and based on the test taker’s answers, the question types and difficulties adjust with each answer. This type of test allows for a greater level of accuracy in evaluating a prospect’s abilities. For the most part, correct answers beget more difficult questions while wrong answers will reduce the difficulty of proceeding questions.
It's important to understand the difference between the ASVAB Standard Scores, and the ASVAB AFQT score. Test takers will receive a separate score for each of the nine sections on the ASVAB. These scores are known as Standard Scores. A Standard Score is used to determine how the test taker compares to the "average" 18-23 year old American on that part of the ASVAB. Not long ago, a large number of people in this age group were given the tests, and these results are the benchmark for Standard Scores. Around half the people in this age group will score a 50 or higher, and about 16% will score a 60 or higher. In other words, the scoring is based on a standard bell curve distribution. Standard Scores are very important when it comes to determining which military job a person will be assigned to.
In the Navy, the rank of Admiral of the Navy theoretically corresponds to that of General of the Armies, though it was never held by active-duty officers at the same time as persons who held the rank of Fleet Admiral. George Dewey is the only person to have ever held this rank. After the establishment of the rank of Fleet Admiral in 1944, the Department of the Navy specified that the rank of Fleet Admiral was to be junior to the rank of Admiral of the Navy. However, since Dewey died in 1917 before the establishment of the rank of Fleet Admiral, the six-star rank has not been totally confirmed.

The best way to answer questions in this section is to read each paragraph twice before you answer. First, read it quickly to get the main idea. Next, read it again, paying more attention to the details that relate to the main point. Then, read all of the questions and refer back to the paragraph to help you choose the best answer. If you take this approach, you will be more relaxed and efficient, and less likely to get thrown off the track by being nervous.
Your success on ASVAB test day depends not only on how many hours you put into preparing, but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking ASVAB practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a ASVAB practice test, pay special attention to these three groups of questions:
As of 31 December 2010, U.S. Armed Forces troops were stationed in 150 countries; the number of non-contingent deployments per country ranges from 1 in Suriname to over 50,000 in Germany.[30] Some of the largest deployments are: 103,700 in Afghanistan, 52,440 in Germany (see list), 35,688 in Japan (USFJ), 28,500 in South Korea (USFK), 9,660 in Italy and 9,015 in the United Kingdom. These numbers change frequently due to the regular recall and deployment of units.
The ASVAB was created in 1968. By 1976, all branches of the military began using this test. In 2002, the test underwent many revisions, but its main goal of gauging a person’s basic skills remained the same. Today, there is a computerized version of the test as well as a written version. The Department of Defense developed this test and it’s taken by students in thousands of schools across the country. It is also given at Military Entrance Processing Stations (MEPS).

A military or an armed force is a professional organization formally authorized by a sovereign state to use lethal or deadly force and weapons to support the interests of the state. It typically consists of branches such as an Army, Navy, Air Force, and in certain countries the Marines and Coast Guard. The task of the military is usually defined as defense of the state, and its citizens, and the prosecution of war against another state. The military may also have additional sanctioned and non-sanctioned functions within a society, including, the promotion of a political agenda, protecting corporate economic interests, internal population control, construction, emergency services, social ceremonies, and guarding important areas. The military may also function as a discrete subculture within a larger civil society, through the development of separate infrastructures, which may include housing, schools, utilities, logistics, health and medical, law, food production, finance and banking.

Either because of the cultural memory, national history, or the potentiality of a military threat, the militarist argument asserts that a civilian population is dependent upon, and thereby subservient to the needs and goals of its military for continued independence. Militarism is sometimes contrasted with the concepts of comprehensive national power, soft power and hard power.
In the 2000s, women can serve on U.S. combat ships, including in command roles. They are permitted to serve on submarines.[39] Women can fly military aircraft and make up 2% of all pilots in the U.S. Military. In 2003, Major Kim Campbell was awarded the Distinguished Flying Cross for landing her combat damaged A-10 Thunderbolt II with no hydraulic control and only one functional engine after being struck by hostile fire over Baghdad.
