After adopting the test in 1976 the test became a way of indicating whether or not an individual was 100% qualified to serve. As previously mentioned this aptitude test has a colorful history. That is because it underwent a dramatic change in 2002 and another dramatic change in 2004. The change that occurred in 2002 expanded the categories of the test and the overall difficulty. This can be seen by the addition of all of the diverse categories below:
The remaining six sections on the ASVAB are used to drill down and determine what job you are best suited for in the military as these scores will provide in-depth insight into your knowledge, skills and interests. These six sections are: General Science (GS), Mechanical Comprehension (MC), Electronics Information (EI), and Assembling Objects (AO), Auto Information (AI) & Shop Information (SI). Please note: AI and SI are combined into one single score (labeled AS) on the paper and pencil test.
Don’t let the PC section of the test throw you for a loop. Unlike the individual multiple choice questions in other sections, here you will need to read a paragraph and answer several questions in a row based on that one paragraph. The people who designed this section of the exam really knew how to make sure you are able to read detailed (and often boring) documents, remember the details of what you read, understand why they’re important, and be able to pick out the key concepts they illustrate. When you read each paragraph, it’s helpful to know the kinds of questions you’ll be asked at the end. There are basically four kinds of questions to test your comprehension:
The ASVAB is a population-referenced exam, which means that the score you receive for the ASVAB is not an exact measure of how you scored on the test, but rather how you scored in relation to a national control group who took the test in 1997. Standard Scores are used on the ASVAB: in each subtest, about 50% of the population received a Standard Score of 50, while only 16% scored over 60. You will receive an estimated score after taking the paper test and official scores later through your recruiter, usually within days. You will immediately receive your scores upon completing the computer test.

Additionally, all services except for the Air Force have an active warrant officer corps. Above the rank of warrant Officer One, these officers may also be commissioned, but usually serve in a more technical and specialized role within units. More recently, they can also serve in more traditional leadership roles associated with the more recognizable officer corps. With one notable exception (Army helicopter and fixed-wing pilots), these officers ordinarily have already been in the military often serving in senior NCO positions in the field in which they later serve as a warrant officer as a technical expert. Most Army pilots have served some enlisted time. It is also possible to enlist, complete basic training, go directly to the Warrant Officer Candidate School at Fort Rucker, Alabama and then on to flight school.

The way to prepare for this exam is study hard and then quiz yourself with plenty of practice ASVAB tests. Remember that the exam is identical for all branches, so an Army ASVAB practice test is exactly the same as an ASVAB practice test for the Navy. The most important components of the test are the ones that count towards the Armed Services Qualifications Test, or AFQT. These sections are Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Math Knowledge. For tips and strategies for success on these questions, be sure to review our article on ASVAB Test Prep.
A military recruiter determines if the candidate is a possible recruit. A recruiter will ask about marital status, health, education, drug use, and arrest record. It is important for the candidate to be upfront and truthful when answering questions. Once the recruiter has determined the individual is qualified for additional processing, the ASVAB is scheduled. A physical examination may also be conducted at the time of the test. 
Military law introduces offences not recognised by civilian courts, such as absence without leave (AWOL), desertion, political acts, malingering, behaving disrespectfully, and disobedience (see, for example, Offences against military law in the United Kingdom).[23] Penalties range from a summary reprimand to imprisonment for several years following a court martial.[23] Certain fundamental rights are also restricted or suspended, including the freedom of association (e.g. union organizing) and freedom of speech (speaking to the media).[23] Military personnel in some countries have a right of conscientious objection if they believe an order is immoral or unlawful, or cannot in good conscience carry it out.
The Armed Services Vocational Aptitude Battery (ASVAB) is one of the most widely used multiple-aptitude test batteries in the world. It was originally designed to predict success in military occupations and is used today to help both those considering entering the military (mostly high school-aged students, but also anyone who is eligible to enlist) as well as those not interested in military service (who comprise the majority of current ASVAB test takers) what sort of career may be the best fit for them. Scores from the ASVAB can be used when enlisting in the military. Students interested in taking the ASVAB should check with their high school to find out when and if the ASVAB will be offered at their school. If it is not offered, students should meet with their guidance counselor to determine if it is possible to schedule a testing session in the future. There is no cost to take the ASVAB.
After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
Less hot under the collar than This Year's Model, Armed Forces was partly inspired by Elvis Costello and the Attractions' 1978 American tour. The songs are set to deceptively poppy arrangements that use plinky Abba keyboards ("Oliver's Army," a hit single about mercenaries), Beatles-ish devices (the fade on "Party Girl"), and whimsical waltz-time signatures ("Sunday's Best") to mask their core cynicism. "Goon Squad," "Busy Bodies," and "Accidents Will Happen" are among Costello's most melodically powerful songs to this point, leading the way to the masterful Get Happy!!. --Barney Hoskyns
The primary reason for the existence of the military is to engage in combat, should it be required to do so by the national defence policy, and to win. This represents an organisational goal of any military, and the primary focus for military thought through military history. How victory is achieved, and what shape it assumes, is studied by most, if not all, military groups on three levels.

These scores include your Armed Forces Qualification Test (AFQT) score as well as your scores on each of the 9 individual subtests that make up the ASVAB.  When you get your report, the most important score you will want to look for first is your AFQT score.  This score determines your eligibility to serve in the military and to enlist in the U.S. Marines you need to have achieved a score of at least 32.

What is the military? In simple terms, the U.S. Armed Forces are made up of the five armed service branches: Air Force, Army, Coast Guard, Marine Corps, and Navy. There are three general categories of military people: active duty (full-time soldiers and sailors), reserve & guard forces (usually work a civilian job, but can be called to full-time military duty), and veterans and retirees (past members of the military). And of course there are the millions of family members and friends of military members, past and present. But you're here to learn more about the military. There is much to learn! So first the basics. Exactly who is in charge?
After the final ability estimate is computed, it is converted to a standard score on the ASVAB score scale that has been statistically linked to the ability estimate through a process called equating. Equating studies are conducted for every paper and pencil ASVAB form to ensure that scores have the same meaning regardless of which test form the examinee receives.

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.

After a candidate has completed the ASVAB they must wait one calendar month before retaking the exam. An additional calendar month must pass before retesting a second time. Six calendar months must pass before retaking the test a third time. The scores received from the ASVAB may be used for enlistment for up to two years from the initial test date. 
The Student ASVAB is the most flexible of the exams. It is typically provided to high school students to help them assess their skills, job prospects, potential military positions, or college majors. The ASVAB for students is essentially the same as the MET ASVAB exam, only students are not necessarily testing for positions within the military. The students’ school counselors examine their scores and help them decide on what to do after graduating from high school. This test is still an important component of a student’s education because it can help them identify their strengths and weaknesses and help set them on the right track for their future career goals.
If you are enlisting in the military, good - a patriotic journey, where you can build skills and see the world. However there is one thing your recruiter didn't tell you. Your ability to get into a department that you want, depends on how well you can take a quiz - just like you did with the SAT, or whatever those test are called in current times. Those test asked those really stupid questions about the cost of ice cream if a train leaves New York at 4:00 and it is 20 degrees on Colorado. This book will teach you how to answer those ridiculous questions that WILL control your destiny. Get a copy and memorize it... then serving your country will lead to a great career.
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.

The content of the test has been clearly laid out, but there is still a ton of information concerning the actual place where the test is administered and the time that is allocated for each section. The computerized test is administered in a “military entrance processing station” (MEP) or a satellite region that is identified as a “military entrance tests site” (MET). The difference in the two locations is that the METs are the places that are responsible for administering the written test, while MEPs are the places that administer the computerized tests.
